PART 4: FILTERS

Unfortunately nowadays we have to fight spammers and use our resources to stop this annoying peope from reaching our clients.

I am including clamav (antivirus), spamassassin and razor.

Architecture:

Qmail-smtpd instead of using the qmail-queue is now invoking qmail-scanner-queue who takes care of invoking clamav, spamassassin and also doing some scans on it's own.
