Sendmail usually delivers regular mail on an almost instant basis. What
I'm getting it a feel that qrunner is not passing the mails from the
qfiles directory for sendmail to deliver. The machine in question has
around 15k uses on it, and they have almost instant mail delivery through
sendmail for regular mail. When a mail comes to the list through sendmail
initially, it gets delivered through the mqueue for sendmail and is posted
to the qfiles of mm almost instantly. However that is where the holdup
is. Qrunner doesn't seem to be dealing with these files well at all.
They are sitting in the qfiles directory and are being delivered or sent
out at a rate of 1-2 per minute.
I don't see an smtp-failure log to check. If there are any features for
debugging I can turn on in MM please let me know. Lock logging is the
only thing I could find initially.
