Mqueue.in just keeps growing...

Well I followed a lot of the suggestions for increasing performance, and
although MailScanner is working a little better, it still cannot keep
up. DNS performance is quick. I do not have the latest spamassassin
version, but based on the fact that most spam is being caught by
Sendmail now (as described below), I wouldn't think that is the problem.

 

I added the greeting delay to sendmail, am now checking Spamcop and XBL
at Sendmail level, and although tons of spam is now being caught before
getting to MailScanner, my mqueue.in is at 30k, incoming is at a
constant 180 and now mqueue is hovering around 2k. Mail is coming
through but way too slow. Also, cpu is just pegged at 100% with several
MailScanner processes, Sendmail processes, and kblockd/0 and kblockd/1
splitting up all cpu. I'm starting to wonder if after the reboot
something has degraded my disk performance and now there isn't enough
cpu for MailScanner to handle the number of messages coming in?

 

I may have to resort to setting up MailScanner on another system at this
point.

 

Thanks for all the suggestions, and if anyone has any other ideas,
please let me know.

 

Thanks,

Max
