[cobalt-developers] RE: NOQUEUE: IDENT...did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA

["Phil Lewis" <phil@xxxxxxxxxxxxxxxxxx>]

I've got several logs to compare over the last several days (sendmail
maillog.1, .2, etc), and I find a DIRECT correlation between reject messages
(grep for ordb / grep for NOQUEUE) These are almost the same number.  It is
most notable when we had a spike of 2500 spams (=ordb.org reject messages)
and my NOQUEUE count went to about the same number; maillog from the
following day, both counts were back down to 95 or so, two days ago, counts
were nearly same, etc.

Sooo, my guess is that the DNSBL activity severes the connection so abruptly
that this error is generated.  BTW, I implemented it in cobalt.mc with

FEATURE(`dnsbl', `relays.ordb.org', `Rejected - see http://ordb.org/') dnl,

which has to be m4'd properly, etc.

I'm interested in observations about this.
