To those who have kindly told me to go to the Sendmail groups, I suspect
Cyrus plays a part in our problem. I'm now fairly certain that our
access db is misconfigured, with the reason stemming from using
"To:domain.tld RELAY" as a workaround for Sendmail not delivering to
Cyrus many moons ago. I don't think we should need to do this, but I
distinctly recall it NOT working if we didn't have it in there. I
suppose the 'duct tape' is coming unglued now. I'm currently working on
putting together a development machine to try out 2.3.7 and removal of
the aforementioned lines in access db.
Any pointers on whether my hunch about the access file is correct or not
are welcome.
Allowing sendmail to relay based on header information is a recipe for
disaster. It's possible that this is the cause of your problem, if
sendmail is accepting messages from dictionary attacks and cyrus is
refusing to deliver them.
