I'm not sure if this is appropriate for the qmail list, but here goes...
On two occasions now I've had qmail suddenly stop processing outgoing (only)
mail. I have not been able to correspond this to any
events and there were no changes to the qmail configuration, firewall or
internal (behind the firewall) mail server at either failure.
At both times, the mail server was running happily with the qmailqueue patch
for months.
At the first failure, I tried queue-fix, re-creating the /var/qmail/queue
dirs, and changing the QMAILQUEUE env variable from pointing to our
virus filter to its original destination of qmail-queue. What finally fixed
it, however, was re-installing qmail from a virgin qmail tarball without the
qmail queue patch.
What's also odd is that the error message was different both times. The
first, I got:
deferral:
<IPAddr>_failed_after_I_sent_the_message./Remote_host_said:_451_qq_write_err
or_or_disk_full_(#4.3.0)/
The second time:
deferral:
<IPAddr>_failed_after_I_sent_the_message./Remote_host_said:_451_qq_internal_
bug_(#4.3.0)/
Again, both times the fix was to re-install qmail without the QMAILQUEUE
patch.
SO, I believe this patch to be mature and widely used. I have no idea why
this is going on and why I haven't seen similar complaints in the list
archives.
It's occurred on both a RH6.2 system and RH7.0 system, both instances were
running the most current fixes.
The box delivers all its mail internally via smtproutes.
Any ideas? Thanks!
