Has anyone seen when the load on a MailScanner server

[Richard Mealing]

I’m not sure that is correct, but I may be wrong too!

# If more messages are found in the queue than this, then switch to an
# "accelerated" mode of processing messages. This will cause it to stop
# scanning messages in strict date order, but in the order it finds them
# in the queue. If your queue is bigger than this size a lot of the time,
# then some messages could be greatly delayed. So treat this option as
# "in emergency only".
Max Normal Queue Size = 2000

So it just stops in the date order and goes for what is top of the queue. I set mine to 2000 but it never reaches that now I have made all my changes.

You should look into tmpfs, it has brought down the load on my servers considerably. I use it for a few things now –

Incoming Work Dir = /tmpfs
SpamAssassin Cache Database File = /tmpfs/SpamAssassin.cache.db
SpamAssassin Temporary Dir = /tmpfs

Maybe run some gstat commands and check your disks are behaving. If not, then implement tmpfs.

Thanks!
Rich

What is happening is your queue is exceeding the threshold set (800 by default I think) where MailScanner just starts to process the email without scanning it. If your server is getting hit by a surge of email and MailScanner cannot keep up, it stops doing checks.
Of course, I could be wrong. Happens a lot.

You probably hit a timeout somewhere. Can you find out from the logs which component times out?

Gets too high like 5 or 6 that MailScanner marks all messages as spam ? If you have seen this is there something we can change that changes the process ?

Thank you
