Are you running a local caching nameserver on your MailScanner box?  Sounds
like it could be DNS latency killing you.

Subject: Mailscanner treats the mails very slowly

Hello all,

Since many days our MailScanner server have a curious
behavior:
- Most of the time they work slowly (less than 50 mails by minute are
treated) which causes latency to mail delivery (up to 4 hours)
- Sometimes, they work normaly and they can empty the queues.


First we suspected an issue between the Mailscanner server and the Exchange
servers. But after many tests all seem to be OK on this point.


When we disable SpamAssasin from the mailscanner.conf,
the queues 
decrease quickly, but after hours the queues increase
again.
When we disable the Anti-virus from mailscanner.conf,
we have no improvement.
When we diable Mailscanner, and use only postfix, we
have no problem.

Volume : 150 000 messages per day
Hardware : 1 Pentium Xeon 2.4G, 1.5 MB RAM, 36G SCSI
HDD
Software : RHE3, Mailscanner 4.40.11, Postfix 2.2.1,
SpammAssassin 3.0.2, Kaspersky 5.0
RBL : Postfix (SpamCop, ORDB, SPAMHAUS); None in
MailScanner, all in SPAMASSASSIN
Average Load : Around 6

Is anybody can help us please, we are in dead end ?

Stephane
