Has anyone seen when the load on a MailScanner server

[Philip Parsons]

I will look into the queue size setting.  But this does not seem to be the issue. What happened is all the emails every single one got marked as spam so where not delivered even the white listed ones.

Thank you

See ... my wife was right. I am wrong all the time.

On the same note, I am seeing similar behavior on a lab server I just built testing out Ubuntu 14.04. I will email results when (if) I have them.

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!

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 ?
