Sorry about that - it is fresh installed Slackware 9.0 with 2.4.21
kernel (to which I applied a patch which disables write access to
/proc/kmem - but this shouldn't be a problem, right?) and _without_
loadable modules support.

Actually the Mailman's heavy processor usage is constant. All the
time. Non-stop.

Actually there are 2 Postfix' running on the system (one is listening
on SMTP port and sending mail to MailScanner's incoming queue, the
other one is grabbing what it gets from MailScanner's output and
actually sends mail). MailScanner is using SpamAssassin "on his own",
so Postfix doesn't have to mess with it.

I don't fully understand your point here.

Ugh... :) Been using sendmail for few years but never had to use those
nasty features. ;-).

The funny thing is, that all works fine on some other installation,
which is actually identical. I don't understand...

Thanks!
