Hi, Thanks for tips. We have Antivirus standard (Bitdefender), mxGuard with INVURI and MessageSniffer. I cleaned up rules.ima for old an unused rules. The file is now below 100k, before it was 160K. I heard, that a big rules.ima could be one reason for big cpu loads. I think, i see the result already, but it's 5pm here and the people are leaving their offices now, which reduces the load anyway. i will check if we have dead DNSBL and/or redundant DSNBL. I see the problem to trash all the incoming crap before it arrives the mail server. But my maybe naive question is: A mail server should be capable to handle all incoming mails by itself? I'm not talking about trillions messages per day, only 10000, which is not really a lot, i think. Or is this a problem related to IMail?

What else do you have running in terms of spam and virus filtering? I would check for dead blacklists, which can delay mail processing and lead to overload, as well as check your average message processing time in the logs. Anything over two seconds per message with all spam and virus filtering would indicate a problem in your filtering configuration.

The Queue Manager needs more CPU power, more than expected. We have about 10000 Mails "local deliver" per day and 3500 "Remote Deliver per day. I'm in trouble to accept that 200 Domains are to much for this server. Any idea to fix this? Any finetuning which i can apply?
