#!/bin/sh
exec /usr/bin/spamd -x -m 8 -u vpopmail -s stderr 2>&1
That's a good start.
What are your load number looking like? Pretty low I expect.
I'd open that puppy up. You can handle way more than 25 connections.
I'd go back to the default value of 100 for starters, and double the
number of spamd children. Then keep an eye on things. You don't want
to get so many spamd instances running that you start swapping ram.
Find a good comfortable number for spamd children (this is what will
eat your ram and cpu), then adjust your total smtp sessions to fit.
You should have many more (2-4x) smtp sessions available as spamd
children.
With that many domains and users, there is probably a good deal of
mail queued up in other servers, which is why you're getting pounded
so hard. You might need to turn off spamassassin temporarily to get
past the wave, but I'd only do that as a last resort. What you have
here is a good opportunity to do some serious tuning. :)
Well Eric, thanks for your reply.

Would you suggest stepping spamd childs from 8 to 16 and incoming

Serious tuning (or tuning at all) its the hardest part!
thanks!
