Hi all,
I'm having an issue with my qmailtoaster box and I don't know hot to
handle
it.
My qmailtoaster box acts as a front end for an exchange server that
forwards
all e-mails from internal users to this box an also e-mail from
internet are
first received from this box and then forwarded to exchange.
From time to time e-mails stacks in the queue of exchange and when
exchange
tries to forward e-mail to qmailtoaster box the following message
appears:
qmail-smtpd: qq soft reject (mail server temporarily rejected message
(#4.3.0)): MAILFROM:<[email protected]> RCPTTO:[email protected]
The mails stuck in the queue are normal e-mail from my users and some
times
contains attachments,
Any idea for this?
We can make lots of guesses, but without logs they will only be guesses.

Right. The qq soft reject can be caused caused by a number of things. In
general though, they tend to be related to the internal queue, and
related processes such as scanning.
Given that your description seems to indicate that the problem
correlates with exchange releasing a large volume of email at once, I
would guess that scanning is perhaps the bottleneck. Have a look at the
spamassassin log and see what's going on there. You'll likely want to
increase the number of child processes.
If that's not the problem, then check clamav, then perhaps run the
queue_repair.py utility.
My guess is that adjusting your spamassassin configuration might help
though. You might also want/need to adjust the configuration such that
intra-domain email is not scanned for spam. This would be the normal
'stock' configuration for QMT, but when used in conjunction with
Exchange, I think that a few adjustments would need to be made to
achieve this behavior. I'm not sure off hand what adjustments are
necessary for this, but I expect someone else here will be able to say
for sure.
Do we have a wiki page yet that addresses how to configure QMT to be a
front end for Exchange? Anyone care to do one if we don't?
