RE: Folks using amavisd-new and SA...

Just a quick question to those that are using those two together.

I have:
$max_servers  = 10;
$max_requests = 15;

in amavisd.conf.

But the box's load average seems to be hovering around 2.00 all the time. 
Sometimes a little lower, sometimes higher.


That is low for a quad CPU system. You want to keep load under 2.00 *per 
CPU*.




Quax 500mhz Xeon, ultra 160gb disks, 1gb RAM. It's a PowerEdge 6350.

What do you guys have set for max_servers & stuff and what kind of 
hardware? What kind of performance are you seeing?




Question: how many messages per day pass through SpamAssassin?

And how well have you found amavisd-new, postfix and SpamAssassin to 
interact?




Excellent.


(note: please don't tell me to switch to mailscanner yet. hah.)


I never would.

This setup has been working well for quite a while but I'm almost wondering 
if it's time to upgrade.




Question: on average how long does it take amavisd-new/SpamAssassin to 
process a message?



Has greylisting helped you out at all?



It can make a hugh difference. If you decide to go with it you should look 
at some form of selective greylisting. I also use a short (59 second) delay.



Thanks!

Make sure your Postfix config allows 10 concurrent connections
(master.cf):

smtp-amavis unix -  -   n -   10  smtp

If that 10 is a 2 that's the problem.

I have it set at 2 for a hobby server and 4 for a low-load server.

Been running great for me for a few years.

Yep, if your users will put up with the delay.
