####### INTRODUCTION #####################################################
#
# This is The IDA Sendmail Master Configuration File--a completely
# independent development having nothing to do with the version
# distributed by Berkeley. In order to work properly, it requires
# a set of new functions implemented by the IDA Sendmail Enhancement
# Kit, available from your nearest comp.sources.unix archive.
#
# Get it today, tomorrow they might have a disk crash!
#
# IDA is an abbreviation of "Institutionen for Datavetenskap",
# which is Swedish for "The Department of Computer and Information
# Science". Under no circumstance should it be confused with the
# IDA that stands for the Institute for Defense Analysis, with
# which the author has no relationship to nor wish to become
# associated with.
})dnl ### End of M4COMMENTS ###
####### REWRITING STRATEGIES #############################################
#
# Ruleset 3 completely canonicalizes addresses to an internal
# format, which looks like a modified RFC822 source route.
# The internal canonical form is documented in the comments
# preceding Ruleset #7 which is called internally by Ruleset #3.
#
# The "domain" will be mapped to its full, official domain name
# using the TCP/IP name server and a dbm domaintable. !- and
# ::-style paths are rewritten into RFC822 routes internally.
# Resonable mixtures of !-, %-, and RFC822 routes are resolved,
# either using straight domain preference, or using heuristics.
# Some effort is made to repair malformed addresses.
#
# This format is used in all internal rulesets until finally
# rewritten by the mailer dependent rules or by ruleset #4,
# where they are fully transformed into the mailer's preferred
# address syntax. Three
# kinds of mailers currently exist:
#
# [1] Domain based mailers, for which the official domain names
# are used and routes are given in the %-format for header
# addresses and envelope recipient addresses, while
# envelope return paths are kept in RFC822 route syntax.
# Typical examples of this type are the TCP/IP and LOCAL
# mailers.
#
# [2] Domain based mailers with flat node name mappings. These
# use full domain names in header addresses but translate
# envelope domains to names relative the actual network's
# name space. Two mailers fit into this category: The DECnet
# mailer, which map domain names to DECnet names, and the
# UUCP-A/B mailers, which map domains to UUCP node names.
# Both the DECnet and the UUCP worlds use flat namespaces.
# The DECnet and the UUCP-B mailers essentially uses type I
# routes while the UUCP-A mailer uses type III routes (ie,
# !-paths).
#
# [3] UUCP !-path based mailers. This mailer type rewrites all
# addresses into !-paths, both header and envelope addresses.
# Header addresses are made relative the remote node by
# removing "remote!" from them or prefixing "localhost!" to
# them. UUCP nodes with domain names are translated to their
# UUCP equivlanents.
####### SENDMAIL CONFIGURATION EXTENSIONS ################################
#
# This is a short table describing extensions to the configuration
# language. See the reference guide for a detailed definition.
#
# Option "/" will turn on general envelope/header specific
# rewriting. Mailer specific e/h rulesets are given as in
# "R=14/15", where ruleset 14 is used for envelope recipient
# addresses and ruleset 15 for header recipients.
#
# The M_FROMPATH (p) flag will work for mailers that use "From_"
# line envelopes as well as SMTP mailers.
#
# The M_RELATIVIZE (V) flag has been added, which make all header
# lines relative the recipient host by removing "remote!" or
# adding "localhost!".
#
# TCP/IP nameserver lookups are extended with a default argument,
# as in "$[ hostname $: default $]". The "default" string will be
# returned if the host isn't known to gethostname(3).
#
# General dbm database functions have been added. The option "K"
# will declare a dbm database and associate it with a letter,
# which later on is used in constructs like:
# "$(x key $@@ arg $: default $)"
# The "x" is the one-letter name of the database, the "key" is the
# lookup string; the optional "arg" is then sprintf(3)'ed through
# the result, if found. The whole expression evaluates to
# "default", or "key" if "$: default" is not present, if the "key"
# can't be found in the database. The "@@" database is
# automatically connected to the aliases(5) file.

####### M4 IDENTIFIERS ###################################################
#
# NOTE: Be aware that this is an m4 source where curly braces are
# used as quote characters. You will lose heavily if you care-
# lessly mention reserved m4 words or use curly braces where you
# shouldn't.
#
# The following is a list of all m4 identifiers used in this file.
# All of them are optional.
#
# ALIASES
# Name of the aliases file, defaults to sendmail's default.
# ALWAYSADDDOMAIN
# If defined, local mail will always have the full domain
# attached to the address. The default is to retain the
# domain if already present, but not add it to local addresses
# without domains. This only effects the local mailer.
# ALTERNATENAMES
# A list of alternate names for which mail is handled on
# this machine. This differs from PSEUDONYMS in that
# mail to a PSEUDONYM is equivalent to mail to the main
# name of this machine. But we may also handle final
# delivery of mail to other names, either with special
# mailers defined in the mailer table, or with use
# of the extended aliasing facility. Used only in
# ruleset #29 for stripping source routes through us
# based on both pseudonyms and alternate names.
# BANGIMPLIESUUCP
# If defined, will assume that all !-paths with leading,
# unqualified nodes resides in the UUCP pseudo-domain.
# Will otherwise try to qualify node using the name server
# and domaintable, retreating to .UUCP if unknown by them.
# BANGONLYUUCP
# If defined, a .UUCP qualification will only be added
# to an unqualified domain if the domain is delimited
# with a !.
# DECNETNAME
# This node's DECnet name as printed by the nodename command.
# Define if this host is a DECnet/Internet gateway. Routes
# mail sent to host::user and user@@host.dnet via mail11v3.
# Will also route user@@host.hepnet, user@@host.decnet, and
# user@@host.span if UIUC is defined. Sendmail must be compiled
# with #define MAIL11V3 in src/conf.h .
# DECNETNODES
# A file containing DECnet host names. Used in combination
# with DECNETXTABLE to determine delivery through the DECnet
# mailer and when to expand flatspaced DECnet host names into
# domains. DECNETNODES may be a list of domains, an absolute
# file path (first char /) or a program (first char |).
# DECNETXTABLE
# The DECnet translation table. Returns a node's DECnet
# host name if given its domain name. (Dbm file, see
# ruleset 24 for more info).
# DEFAULT_HOST
# Explicit host name, replaces automatic definition of $w.
# DEFAULT_DOMAIN
# The string that (+ ".") will be attached to $w to
# form $j, this node's official domain name. Only define
# this if $w doesn't already include your full domain
# (ie, as returned by gethostbyname(<yourhost>)).
# DOMAINMASTER
# Obsolescent. Use ALTERNATENAMES (which see) and a mailer
# table entry. Was intended to allow handling mail for a parent
# domain for which there is no machine. For example, at
# uiuc, machine uxc.cso.uiuc.edu can handle mail for uiuc.edu.
# by sending them to the PH mailer. But with the extensions to
# the mailertable, the same effect is achieved by defining an
# entry: PH!uxc.cso.uiuc.edu uiuc.edu
# in the mailertable source. An entry for uiuc.edu would still
# be needed in ALTERNATENAMES to strip source routes.
# DOMAINTABLE
# Dbm database used for hostname canonicalization, ie.
# to find the official domain name for local or otherwise
# unqualified hosts.
})dnl ### End of M4COMMENTS ###
ifdef({M4COMMENTS},{dnl -Divided this to avoid overflowing m4 buffer.
# FORCE_NAMED
# Set the I flag to force host name lookups to go through the
# domain name server. Otherwise if the nameserver isn't
# running, sendmail will assume that /etc/hosts is complete.
# You want to use this if you're doing MX forwarding. You
# DON'T want to use this if you're not running the nameserver.
# GENERICFROM
# A database mapping actual user names to generic user
# names. Used instead of HIDDENNET in a heterogenous
# environment.
# HIDDENNET
# Points to a file containing a list of host names, one
# per line. Mail from users on any of these hosts will
# have the host name substituted for our host, $w.
# HIDDENNET may be a list of domains, an absolute
# file path (first char /) or a program (first char |).
# HIDDENNETHOST
# The fully qualified domain name to use instead of $w with
# HIDDENNET.
# LIBDIR
# The directory that will hold most data files, including
# sendmail.{hf,st}; defaults to /usr/lib/mail.
# LIUIDA
# Site specific parts for the CIS Dept, U of Linkoping.
# LOADAVEQUEUE
# The load average at which messages will be queued. Defaults
# to 11. Define as 0 to disable the facility.
# LOADAVEREJ
# The load average at which connections will be refused.
# Defaults to 7. Disable by defining as 0.
})dnl ### End of M4COMMENTS ###
ifdef({M4COMMENTS},{dnl -Divided this to avoid overflowing m4 buffer.
# M4COMMENTS
# Not intended to be defined. If not defined, comments
# which only make sense in the M4 source are excluded from
# the generated .cf file.
# MAILNAME
# The domain name to be used on outbound mail, in place of
# $w. This is mostly useful when it is desired to hide all
# host names in a network, with a common MX name to be on
# outbound mail. If most hosts in the network do not run
# SMTP daemons it is better to not use the real hostname.
# MAILNAME is only used for local names for which no domain
# is explicitely specified. If you wish to hide host names
# that are explicitely specified, you should also use
# HIDDENNET. When MAILNAME is defined it becomes the
# default value for HIDDENNETHOST.
# MAILERTABLE
# A dbm table mapping node names to "mailer:host" pairs.
# It is used for special cases when the resolving heuristics
# of ruleset 26 aren't enough.
# The key may be of the form .subdomain for matching complete
# subdomain families. The value mapped to may be of the
# forms - mailer,host or mailer:host or mailer!host
# The standard should be mailer,host . With mailer!host the
# destination domain is removed from the recipient address before
# mailing. With mailer:host the recipient domain is removed if
# multi-level routing is present. An optional form ':' (i.e.
# missing mailer and host) may be specified to cause mailer
# selection to fail, and force a PATHTABLE lookup.
# In the host portion of mailer,host there may be a %s provided
# that the search key begins with a '.' - the effect is that when
# a match occurs, the component of the actual domain name which
# precedes the '.' in the key will replace the %s.
})dnl ### End of M4COMMENTS ###
ifdef({M4COMMENTS},{dnl -Divided this to avoid overflowing m4 buffer.
# MAILSERVER
# The name of a host on which local mail should be delivered.
# If the mailbox directory is mounted from a remote file server
# you may wish to specify that local mail be sent to the remote
# server for local delivery there. Alternatives are to use
# the RSH_SERVER.
# Important note: If you use the MAILSERVER option, any
# programmatic aliases should be specified with the '|'
# outside the quotes. For example, use
# msgs: |"/usr/ucb/msgs -s"
# Note that the local aliases file is still consulted before
# a decision is made to forward the mail to the MAILSERVER.
# It is not currently possible, however, to consult the
# user's '.forward' file. Hopefully the MAILSERVER will
# mount the same home directories, and will itself consult
# the .forward file.
# If the aliases file is a YP/NIS alias map, the alias processing
# is slightly different. In this case local names are mailed to
# the MAILSERVER for expansion, unless they are qualified with
# a domain recognized as local. Here are some examples.
# list: addr1, addr2, addr3 # Lists ALWAYS sent to MAILSERVER.
# me: you # Sent to server for expansion.
# me: you@@client1.dom.ain # Expanded locally if client1.
# nobody: /dev/null@@localhost # Expanded locally on all clients.
# (This assumes that 'localhost' is defined as a PSEUDONYM).
# recnews: recnews-client1@@client1.dom.ain
# recnews-client1: |"recnews"@@client1.dom.ain
# Mail to 'recnews' should be expanded locally on client1,
# but all other clients will send to MAILSERVER, which will
# forward to client1 readdressed to recnews-client1, and in
# turn it will be expanded on client1.
# NEWALIASES
# This option is obsolete. A better method now exists.
# See below, at the end of the description for this option.
#
# New approach: If you want a non-local alias for
# 'user@@host', list it in the aliases file as
# 'user%host@@localhost'. This will result in a correct
# alias entry, since addresses routed through 'localhost'
# are now automatically sent to the local mailer.
#
# The script 'xalparse.sh' generates the correct format
# aliases file from xaliases.
# NIS_MAILHOST
# Used in conjunction with NIS_MAILALIASES described below.
# Note that the NIS_MAILHOST *** MUST NOT *** be this
# local host, *** NOR *** an MX address for which this local
# host is the best preference handler.
})dnl ### End of M4COMMENTS ###
ifdef({M4COMMENTS},{dnl -Divided this to avoid overflowing m4 buffer.
# NIS_MAILALIASES
# Use the NIS mail aliases before attempting local
# delivery. If a local address is not in the local
# aliases file, the NIS/YP aliases file is consulted.
# If an alias exists and specifies a single mailbox
# address local to this host (domain matches $=w)
# it is delivered to that alias locally. Otherwise
# the mail is forwarded to NIS_MAILHOST via the
# TCPMAILER for alias expansion and delivery.
# *** NOTICE *** In order to not interfere with
# construction of the local alias database rebuilding,
# this option is implemented in such a way that it
# only affects addresses used for actual delivery
# of mail. Test mode ('sendmail -bt') will usually
# not reveal how this is processed. To test this
# option under test mode, specify:
# /usr/lib/sendmail -bt -oMfnobody
# ISOLATED_DOMAINS
# A list of domains which may use TCP/IP delivery. Any
# domain not in this list is assumed to need to be sent
# using RELAY_HOST/RELAY_MAILER. This is useful if a
# site is using the DNS, but has a policy which does not
# allow IP connectivity between internal networks and
# the Internet.
# PATHTABLE
# The heart & soul of this sendmail configuration--the
# pathalias routing table in dbm format, as produced by
# the pathalias program. Either you define this or rel(a)y
# on RELAY_HOST/RELAY_MAILER.
# POSTMASTERBOUNCE
# If defined the postmaster gets a copy of bounced mail.
# Can alternatively be defined to a mailbox name, in which
# case the copy of bounced mail is sent to this mailbox instead
# of to the postmaster.
# PSEUDODOMAINS
# A list of well-known top level pseudo domains such as
# BITNET, CSNET, UUCP, etc. Addresses ending with a top
# level domain in this class won't be canonicalized using
# the resolver to reduce load on the root name servers.
# Note that this variable is independent of the T class
# below. Any "well-known" top level domain that is not
# part of NIC's registered domains may be put here.
# PSEUDODOMAINS may be a list of domains, an absolute
# file path (first char /) or a program (first char |).
# PSEUDONYMS
# Additional names that we are known under (in addition
# to those returned by gethostbyname()).
# PSEUDONYMS may be a list of domains, an absolute
# file path (first char /) or a program (first char |).

# RELATIVIZE
# This option has been removed. It is incompatible with
# the use of MX addresses. The SMTP host still needs the
# full domain name (which may be an MX address) to make its
# forwarding decisions. Relativization for specific domains
# is still possible via mailertable.
# RELAY_HOST & RELAY_MAILER
# Name of the host and mailer to ship unknown recipient
# addresses to.
# RSH_SERVER
# If defined, do local deliveries by rsh'ing /bin/mail
# on the RSH_SERVER host. Make sure that root is allowed
# to remotely login to the server.
# SPOOLDIR
# Directory for sendmail queue files; defaults to
# /usr/spool/mqueue.
# STRICTLY822
# This is obsolete, and is replaced by a changed UUCPPRECEDENCE
# (which you should read). It was used to identify the
# precedence of !/@@. It former function is now the default
# except for UUCP nodes identified in UUCPPRECEDENCE.
# TCPMAILER
# The default TCP mailer to use for SMTP/TCP deliveries.
# Defaults to TCP (as opposed to TCP-D or TCP-U, qv).
# TIMEOUT
# By default the timeout, the length of time the mail sits
# in the queue before being returned to the sender, is
# two days. By defining TIMEOUT to some other value, you
# can change this. For example: define(TIMEOUT, 3d)
# in your 'm4' source would give a three day timeout before
# mail is returned as undeliverable.
# TRUSTEDUSERS
# Trusted users to be added to users root daemon uucp.
# UIUC
# Site specific parts for the University of Illinois at
# Urbana-Champaign. Replaces UUCP mailer with one one that
# accumulates statistics.
# UUCPMAILER
# The default UUCP mailer to use for UUCP deliveries.
# Defaults to UUCP (as opposed to UUCP-A or UUCP-B, qv).
# UUCPNAME
# This node's UUCP host name.
# UUCPNODES
# A file containing names of directly connectable UUCP nodes.
# UUCPNODES may be a list of domains, an absolute
# file path (first char /) or a program (first char |).
# UUCPPRECEDENCE
# A file containing names of UUCP nodes which generate
# hybrid !/@@ addresses for which the '!' should be given
# precedence. Normally 'u!x@@d' is parsed as '@@d,@@u!x' but
# if 'u' is in the UUCPPRECEDENCE list, and if the
# mail originates at 'u.UUCP' (must be the same 'u'),
# then 'u!x@@d' is parsed as '@@u!@@d,x'.
# UUCPPRECEDENCE may be a list of nodes, an absolute
# file path (first char /) or a program (first char |).
# Please note that this functionality is only available
# if your 'rmail' invokes 'sendmail' with the flags
# -oMrUUCP -oMsnodename.UUCP
# UUCPRELAYS
# Name of file containing names of known (UUCP) relays.
# Header addresses containing paths through any of these
# will be shortened by having the path to the relay removed.
# (It is assumed that paths to each of these are known to
# everybody) UUCPRELAYS may be a list of domains, an absolute
# file path (first char /) or a program (first char |).
# UUCPXTABLE
# A table mapping domain node names to UUCP node names.
# Used in envelope addresses sent using UUCP/rmail.
#
# The following are still experimental:
# XEROXGV & XEROXNS
# Default gateways for unspecified Xerox Grapevine and XNS
# addresses.
# XNSDOMAIN
# The name of the XNS Gateway domain {from the XNS side}.
# XNSMAIL
# The name of your XNS Mail Gateway program.

# TCP/IP mailer specification
#
# The TCP mailer is the normal choice for SMTP/TCP delivery, but a
# couple of variations exist for compatibility with mailers that
# need special address formatting for indirect UUCP and DECnet
# addresses. Both have to be explicitly mentioned in the mailertable
# to be chosen as all normal mail will use the standard TCP mailer.
#
# TCP-A -- make sure address ends with a registered domain, ie.
# strictly legal within the ARPA Internet. If it isn't, we'll
# turn it into a path through ourselves.
#
# TCP-D -- will flatten envelope recipient DECnet domains for
# messages destinated to our DECnet gateway. Unfortunately, our
# (Linkoping) DECnet gateway is too dumb to do this itself.
#
# TCP-U -- is available for hosts which require hybrid addresses
# for deliveries to UUCP destinations. Eg. "bar!foo@@dest.host"
# will be formatted as bar!foo@@dest.host in the output mail,
# whereas the regular TCP mailer will preserve the address in a
# format more closely resembling the address it received.
#
# Both of the above only touch envelope addresses; header
# addresses are still kept in our preferred format. Change the
# R/S settings below if you don't like that.

# #
ifdef({M4COMMENTS},{dnl
# This rule set passes unchanged any valid address which is #

# mailer-specific ruleset to output format the address itself #
# and be sure that S4 does not further alter it. #
# #
# Addresses resulting from S4 are NEVER enclosed in angle #
# brackets. DO NOT CHANGE this, as a some mailer-specific #

# assumes that the address has been reasonably formatted #

# #
# The basic algorithm is to first enclose everything in #
# <angle brackets>. Then each domain is moved out, leaving #
# the unprocessed part treated as the "user" portion still #
# in brackets. This approach permits a simple recursive #
# definition which is modified somewhat to allow iterative #
# processing where possible, and to handle the complexities #
# of the RFC822 source route format. #

# #
# Rule Set #7: Canonicalize address. #
# #
# This is a subroutine to S3. After S3 has done basic #
# repairing of addresses it calls S7 to canonicalize. #
# S7 may also be called to canonicalize internal addresses. #
# DO NOT pass already canonical addresses to S7. However #
# a semi-canonical address, beginning with @@ (NOT %) may #
# be totally enclosed in <> angle brackets and passed to #
# S7 for re-canonicalization, although this should not #
# normally be needed. Addresses canonicalized by S7 #
# are not necessarily fully qualified (see rule set #8). #
# #
# The general internal form of an address is a modified #
# RFC822 source route. An address will be converted first #
# to the form: #
# @@host1,@@host2,...@@hostn,user (Note the ',' not ':' #
# which precedes user). #
# However, the ',' may not really be a ','. It could also be #
# a ':' or a '!'. The choice of ',',':', or '!' serves to define #
# how the host domain was delimited. A ',' represents an '@@', #
# a ':' represents a '%', and a '!' represents a '!'. #
# #
# Note also that the modified form ends with just 'user', not #
# with 'user@@domain'. This format is easier to use internally. #
# After turning into a modified route, the immediate host is #
# single out with angle brackets. This leaves an address of #
# the form <@@host1>,@@host,....,@@hostn,user. #
# #
# Finally ruleset's 1 and 5 convert the initial '@@' into a #
# '%'. This enables rewriting rules to more easily #
# distinguish between sender addresses (with a %) or #
# recipient addresses (with an @@). #
# #
# Ruleset #7 calls ruleset #9 to isolate the user portion #
# of an address. Most of #7 deals with addresses for which #
# the user portion is enclosed in <>, and is already #
# canonicalized. However it is possible to call #7 with the #
# user portion already isolated and canonicalized. #
ifdef({PATHTABLE},{dnl ### PATHTABLE is defined ###
# This is done in the PATHTABLE routing, where it is necessary #

# ruleset #7 supports the following types of address: #

# a!b!@@c,@@d:<x>%f@@e #
# b!c!<x>%d@@a #
# However it does not support an address of the form #
# @@a,@@b:d!e!<x>@@c #
# #
# It should be pointed out that for a complete address with #
# the user portion not yet isolated, there is no such #
# restriction. In that case, ruleset #9 will convert #
# @@a,@@b:d!e!x%f@@c #

# This option is obsolescent. A new, hopefully better
# approach is now availaible. See below, at the end
# of the description for this option.
#
# If defined, will make ruleset 26 return all addresses
# as local. This should be used by the newaliases program
# only when parsing the aliases file if you want to be
# able to handle non-local aliases (ie aliases of type
# "user@@host: whatever"). Note that you can't let
# sendmail rebuild the database automatically if this is
# the case or else those aliases will be thrown away.
#
# New approach: In MAILERTABLE, define a mailer for
# a dummy domain. Route all non-local addresses through
# that dummy domain in the aliases source. The dummy
# domain we suggest is 'new.aliases.UUCP'. This is
# deliberately a PSEUDODOMAIN, so the nameserver is not
# consulted. It is unlikely to duplicate an actual domain.

To: Paul-Pomes@@uiuc.edu
Subject: Changes to Sendmail.mc
Cc: mdb@@kosciusko.esd.3com.com
Thanks for spotting and correcting my misspelling of 'Illinois'.
Here are my latest changes:
Changes to ruleset #7:
This ruleset does the merging of routes. The changes generalize
the address formats permitted in the pathalias table. In particular
addresses of the form 'b!c!u@@a' are now correctly handled. I am not sure
you will want to put such addresses in PATHTABLE, but if you do they will
now be parsed correctly (as a -> b -> c -> u in the example).
Changes to ruleset #9:
I changed the way the choice of interpretation of hybrid @@/!
addresses handled.
STRICTLY822 is now obsolete, and will cause a gentle complaint. Actually
it has become the default. UUCPPRECEDENCE is reinvented, but it must now
be defined as a list (CLASS) of uucp nodes which screw up addresses. An
address: uuhost!user@@domain will be interpreted as
uuhost -> domain -> user
only if: uuhost is in the UUPRECEDENCE list, and the source of the mail
is uuhost.UUCP (the same uuhost). That should take care of most of the
cases of mixed up UUCP addresses while minimizing the risk of accidently
misinterpreting an intended RFC822 address.
Miscellaneous changes:
I removed the RELATIVIZE option. Thanks for pointing out its
undesirability.
I discovered that lines in sendmail.cf such as:
Cw$k
don't actually do anything. It turns out that $ substitution does not occur
while processing 'C' lines. I made some minor changes as a result. The
change most likely to be noticed is that Sendmail.mc will now complain if
UUCPNAME is not defined. (You can probably ignore the complaint, for you have
surely long ago added uucpname.UUCP to the PSEUDONYM list).
Also there are a number of changes and corrections to the documentation
within Sendmail.mc

From: Neil Rickert <rickert@@cs.niu.edu>
To: Paul-Pomes@@uiuc.edu, mdb@@kosciusko.esd.3com.com
Subject: Changes to Sendmail.mc
Here are some changes to Sendmail.mc.
1. Ruleset #13. Modified so that the UUCP mailer will use our UUCP
name regardless of whether our host has an entry in UUCPXTABLE.
This change effects the envelope sender, the header sender, and also
effects alternate header recipients on our host whose domain was
not specified.
The prior behavior was for these addresses to use our uucpname if our
host was in UUCPXTABLE, and otherwise to use 'uuname!full.domain.name!...'.
A header recipient whose domain was entered explicitely is not effected
by these changes.
The changes required use of '$k', so ruleset #13 had to be moved to below
where $k is redefined if UUCPNAME is specified in the m4 file.
2. Ruleset #15. A major rewrite. This ruleset was used for envelope
recipients for the UUCP-A mailer. It has been extended to also be
useful for the UUCP-A envelope sender. The main purpose is to support
the philosophy that the UUCP-A mailer should come as close to providing
Internet style addresses as possible. Thus the full domain name is used
in preference to the UUCP name. For the sender, the address is formatted
as 'full.domain.name!user' since using an '@@' is sometimes incompatible
versions of 'rmail' or its equivalent on the receiving domain. Where
possible, user@@full.domain.name is still preferred for the envelope
recipient.
The changes are handled in such a way that the full domain name is used
even when there is a UUCPXTABLE entry.
3. Ruleset #19. There was a bug. (A $+ was incorrectly entered as S+).
This has been fixed.
In addition, I have commented out all of the UUCPXTABLE specific code
in #19. I don't believe it is needed. The effect will be to make
#19 slightly less aggressive in converting % paths to !-paths.
This code was originally placed there to make the code functionally
equivalent to the original IDA. However the corresponding code in the
original IDA was broken, so didn't work as claimed anyway. Moreover
since we are not converting !-paths to %-paths (as original IDA did)
there is less need to be as aggressive in converting %-paths back to
!-paths. I find it difficult to think of a likely scenario where this
code would actually do anything useful, since the UUCPXTABLE entries
should mostly refer to nearby hosts (typically the primary domain in
a path), and the code only effects domains further away.
It would be my intention to eventually remove this code, but commenting
it out provides the same benefits but allows it to be restored if we
find it is indeed needed. At a later time it can be removed.
4. Changes to the Mailer definitions. The UUCP mailer now uses ruleset #13
for envelope senders as well as for header addresses. The UUCP-A mailer
now uses #15 for envelope senders. The 'p' flag is removed from the
UUCP-A mailer, with a more limited version of the equivalent function
provided instead in ruleset #15.

Here is the explanation for that behaviour.
When the mailer sees an address: a!b%c it presumes a UUCP origin, since
there is a ! but not %. Therefore it give ! precedence. However when it
sees an address: a!b%c@@f.q.d.n it presumes a RFC822 address. Since '%'
is more closely related to RFC822 addresses than is !, it gives precedence
to % over !.
Who says that the machine should strip of the @@f.q.d.n and reparse? Why
can't its reparsing depend on the type of received address? And, by the way,
if the address a!b%c@@f.q.d.n has a UUCP origin, it should be sent to
a -> fdqn -> c -> b. (You can test this with 'sendmail -bt -oDrUUCP').
If you still prefer ! to always have precedence over %, I am attaching a
patch at the end of this mail. It really makes no difference to me, since
I try to avoid such monstrous addresses. I haven't completely decided
which interpretation I prefer. (Note: RFC1123 only SUGGESTs an interpretation).
If Paul has any comments on this issue I would be interested, since he sees
a much more diverse set of mail than I see.
By the way, the patch also adds some documentation to ruleset S3, on the
assumption that if code is not obvious, and is not documented, someone who
doesn't understand it will one day change it.

I have thought out the mods (ruleset S13) a little more carefully since
I sent them to you. Here is a patch.
The earlier version worked, at least according to my tests. But if a
user had typed in the address as: user%full.domain.name
instead of: user@@full.domain.name
it would have had no effect. The new version should take care of that.
Neil.

From: Neil Rickert <rickert@@cs.niu.edu>
To: Paul-Pomes@@uiuc.edu
Subject: Sendmail patches.
Cc: mdb@@kosciusko.esd.3com.com
The Sendmail.mc patches effect the UUCP mailer and the UUCP-A mailer.
First, for the UUCP mailer. The main effect is that a header address
of 'user@@full.domain.name' will now go out as
'full.domain.name!user'. Before this patch it used to go out as
'myuucpname!full.domain.name!user'.
The patch defines ruleset 13 for the UUCP header addresses.
The main purpose is to improve mail headers for MX addresses relayed through
UUCP hosts. It will not effect normal UUCP addresses, nor domain addresses
which are translated to UUCP addresses in uucpxtable.
-
The patch for the UUCP-A mailer consists of changes to ruleset S21.
It requires the code patch to parseaddr.c to be effective. (If the patch
is installed without the code change there are no bad effects - it is just
not fully functional).
The change is as follows:
If a local UUCP neighbour address of 'user@@uuhost.UUCP' is in a header
for the TCP mailers of the UUCP-A mailer, the address previously was sent
out as 'user%uuhost.UUCP@@our.domain.name'. This can result in problems if
the recipient is using a route stripping algorithm similar to that in the
IDA package, for the recipient mailer will reduce the address to
'user@@uuhost.UUCP', and this may prevent replies if uuhost is not on the uumap.
With the change, the address will instead be sent out as
'uuhost!user@@our.domain.name' which is less likely to be stripped with
route stripping algorithms, since the 'uuhost' domain is not qualified.
A second change occurs only for the UUCP-A mailer. Previously an address
'user@@uuhost.UUCP' was sent as 'user%uuhost.UUCP@@our.domain.name' or as
'uuhost!user@@our.domain.name' even if the recipient host is uuhost itself.
With this change, if the recipient domain is uuhost itself, the address
will remain as 'user@@uuhost.UUCP' without the extraneous routing.
It is only this latter portion, for UUCP-A, which will not do anything unless
the code changes are also made.
------------------------------------
The code patch to parseaddr.c is to allow $&x to appear on the left hand side
of a rewriting rule. In the previous behaviour, $&x could be used on the RHS
of a rule, for delayed evaluation of the macro $x. But when used on the
left hand side it would never match anything. With the patch $&x also allows
delayed evaluation as a left matching string, and the matched value - possibly
including null - is assigned to a $n variable.
