Hi You'll probably get a lot of this, but a lot the software you mention is really really old, and I'm surprised you're clamav is indeed getting it's regular updates.
Also a lot of people will recommend NOT using a fast moving linux distribution like Fedora as server. Once you've upgraded spamassassin and clamav then I'd have a look at this for some ideas about getting better performance out of SA.. http://wiki.mailscanner.info/doku.php?id=maq:index#getting_the_best_out_of_spamassassin -- Martin Hepworth Snr Systems Administrator Solid State Logic Tel: +44 (0)1865 842300 > -----Original Message----- > From: Vincenti Francesco [mailto:[EMAIL PROTECTED] > Sent: 19 September 2008 08:35 > To: users@spamassassin.apache.org > Subject: Trobles with spamassassin > > Good morning everybody, > > My name is Francesco, from ThyssenKrupp. > > I'm mailing you for some suggestions about a problem which I > find in my antispam system, based on spamassassin. > > My system has the following characteristics: > > - A two nodes cluster based, active-active, one for > the incoming email and the other for the outgoing email.
