Hi All,
Wondering if anyone can enlighten me on some strange qmail behaviour.
Qmail is currently acting as a primary SMTP forwarder for a client of
ours as well as ourselves.
We also have an upstream relay which is called upon, as far as I'm
aware, when qmail is under a little pressure delivering SMTP.
We had a situation where a destination SMTP host died and qmail started
banking up messages - around 70 or so.
Here's where it gets interesting...we have a monitoring program running
on the qmail host which emails one of our local exchange accounts via
qmail - sendmail actually pumps it out first.
This mail actually came through to us...strangely enough it also went to
our relay-host and then got bumped through to a destination address
completely different from the intended address...this happened to be an
address of one of our clients!
More interesting stuff...30 seconds before the relay delivery message in
syslog we saw a delivery to our client, using the address that our
monitoring mail ended up at, get delivered successfully - now both these
messages use the same queue message ID. Is it possible that qmail ended
up using the same destination address for two different mails?
A bit more info...the first mail to the client shows a successful
delivery...the client end, Mimesweeper, says it received it and pushed
it on, but the actual user says they never saw it...only the second one
from our relay-host.
Has anybody got any ideas as to what the heck is going on?
Cheers,
Darren.
