Just a note.
My mail server is Scalix 10.1 running on RHEL4 on a new pretty good machine.
With Mailwasher installed and running with Scalix, my Load average (from top) is always between 2.3 and 3.5, even without any users logged in.
Without Mailwasher (after I disabled it), my load average is between 0.10 and 0.30.
Ideally, a load average should be below 1.5 IMO. Below 1.0 is even better.
At a load average of 5 or above, servers may stop responding.
Also, regularly, Mailwasher would timeout on certain messages and an error would be recorded in the logs.
On top of that, occasionally, I found out from my users 3 months after I got it up and running, emails would just get black-holed.
And finally, Emails between my two sites were being delayed, most of the time by minutes, a lot of the time by many hours.
As soon as I disabled MailWasher, all those problems went away.
Buyer beware...
