	 * be spotted. Note this is primarily intended for use in the UK,
	 * where such synonyms abound. It does take longer to spot a bad
	 * address, so if you don't need the functionality don't use it -

#define LOOK_FOR_LONGSYNONYMS 1

	/* An extension which allows one of the classes to be nominated
	   as known top domains. If an address ends with one of these to start
	   with, we assume it is fully expanded, and the only point of looking
	   up the name is to find synonyms. Note: this only affects getting
	   the canonical name using BIND. To enable the extension, define
	   TOP_DOMAIN_CLASS to the letter you wish to use. It is suggested
	   that class 't' be used - because this is lower case, no other cf rule
	   set should use this for another reason. However, as a safety
	   measure, the feature is only enabled if there is some data placed
	   in TOP_DOMAIN_CLASS.

	   By default, names are always searched for normally (if
	   NO_WILDCARD_MX) or not really searched for (! NO_WILDCARD_MX).
	   jf 12/90

#define TOP_DOMAIN_CLASS 't'

	/*
	 * By default, during getcanonname, sendmail accesses BIND
	 * with the DEFNAMES and DNSRCH flags set. This means that
	 * partially defined names will be automatically resolved
	 * by BIND. [Note, if TOP_DOMAIN_CLASS is defined, there is
	 * a dot in the name, and the last element is in the
	 * top domain class, the search will take place with these
	 * bits reset.] If you prefer never to use DNSRCH in this
	 * situation, for some reason, uncomment the next line. The
	 * effect of this is that BIND only knows local and global
	 * names. The bits used are refered to as the "SEARCH bits".
	 * The disadvantage of this is that there are ambiguity
	 * problems if TOP_DOMAIN_CLASS is not kept up to date - there
	 * is a small possibility that what is really a full address
	 * from somewhere else will match a local address. Whether you
	 * feel this is a real possibility is a matter of opinion.

/* #define DONT_DNSRCH 1 */

	/*
	 * if IGNORE_SELF_MX is defined, getcanonname fails if the
	 * found name has MX's where the best points to the current
	 * node. The reason for this ``trick'' is as follows:
	 *
	 * Host 'somecompany.com', which has a uucp node name of 
	 * 'somecompany' arranges to have an MX record created, 
	 * pointing to the localnmode as the best preference.  
	 * At the same time, they make sure their uucp name is in 
	 * the uucp maps.
	 *
	 * When any internet user sends mail to 
	 * 'user@somecompany.com' it arrives at the localnode. 
	 * Because the best preference MX is local, the TCP mailer 
	 * is not selected.  There is now a lookup of the PATHTABLE 
	 * database.  This contains a record:
	 *
	 * 	somecompany.com		foo!bar!somecompany%s
	 *
	 * which was generated from the uucp maps, using the 
	 * pathalias function.
	 *
	 * The big advantage of this is that whether to use the relay
	 * or not can be determined by ``samecompany'' - it is a
	 * question of changing the MX entry. The disadvantage is
	 * that you have to be able to cope with ALL local synonyms
	 * yourself - via PSEUDONUMS or via the DOMAINTABLE database.
	 * Otherwise, you may find yourself with bouncing mail.
	 * The alternative technique for routing is to use the
	 * MAILERTABLE to indicate different mailers are required
	 * for particular mail. This requires more local intervention,
	 * but doesn't have any of the problems associated with
	 * this option.
	 *
	 * Generally, if you don't relay or you are using non-IDA
	 * .cf files, it is best to leave the option commented out.
	 * Otherwise, it is up to you - it probably depends on
	 * how many nodes you relay to, and how frequently the
	 * information changes.

/* #define IGNORE_SELF_MX 1 */

	/*
	 * There is always a problem of knowing what to do if
	 * the name server returns h_errno==TRY_AGAIN during getcanonname.
	 * By default, it will return FALSE, but if you define
	 * IGNORE_TRYAGAIN, it will return TRUE. Normally if the 
	 * condition still persists, then it will be met again
	 * during getmxrs, and the mail will be requeued. However,
	 * if you use BIND to resolve names, there is always a possibility
	 * that the wrong action will occur. Probably best only to
	 * set this if BIND problems are common.
