Hello,
We have a bi Xeon 3.2Ghz 4Go memory Redhat EL4 server as a relay
connected to Internet. On that server we have an advanced filter
injecting mail back into postfix 2.5.4 for the anti spam/virus (Sophos
Puremessage).
Time to time we have lot of mail in the incoming queue, "no" mail in the
active queue, the "qmgr "is very" slow and the server is very idle. We
tested the antispam/virus to see if there is a problem but the response
is very good.
When the server start to put mail in the incoming the only way we found
to stop the increase of the queue is to reduce the smtpd connection from
100 to 40, but with that it take lot of time to connect to the server.
One day we have 50000 mails in the incoming and it take lot of time to
the server (with idle cpu) to empty the queue.
