NOTES
-----


ch_ad_type:
	The values come from tb_a.h


ch_chan_out:
	Only set on an incomming (or listening) channel. This
	is the name of the output channel to which any error
	reports are sent. During Submit, if an error report is
	generated, and if this ptr is set then the msg is
	sent back to the originator via this channel. Otherwise
	it is sent via the output channel calculated by the
	routine ch_bind().


ch_chan_type:
	May have one of the following values:
		CH_SHAPER	-	formatter
		CH_IN		-	listener
		CH_OUT		-	transmitter
		CH_BOTH		-	listener/transmitter
		CH_WARNING	-	Warning channel (for qmgr)
		CH_DELETE	-	Deletion of unwanted msgs (for qmgr)
		CH_QMGR_LOADER	-	Loading the QMGR channel (for qmgr)
		CH_DEBRIS	-	Debris cleaning channel
		CH_TIMEOUT	-	timeout channel

	CH_SHAPER - may be flattener, unflattener or a formatter.
	Depending on whether ch_bpt_in &/or ch_bpt_out fields are set.
		ch_bpt_in:
			Channel is a unflattener.
		ch_bpt_out:
			Channel is a flattner.
		ch_bpt_in & ch_bpt_out:
			Channel is a formatter.


ch_cost:
	How expensive is this channel to run. The higher the
	cost the less likely it is to be used. This is an
	important parameter for Submit's ch_bind() routine.


ch_content_in:
ch_content_out:
	Only set on an incoming (or listening) channel. Otherwise NULLCP.
	May have one of the following values:
		"822"
		"p2"


ch_info:
	This is a local string that is specific to a particular
	channel, to be interpreted by that channel in any way
	it sees fit.



ch_mta:
	A relay route for this channel.

ch_access:
	Whether this channel is from another MTA or from local submission
