How many messages are being processed per day? For how many accounts?  And what percentage of those accounts are Windows stations?

The higher those numbers, the higher the likelihood you'll see infected messages reach your mail server.

We process around 2.3 millions messages a month, with about 1.7 million of those blocked as spam at the SMTP level, about 300,000 are blocked as spam by amavis/spamassassin/dspam, another 50,000 or so are tagged as possible spam but still delivered, and maybe 20,000 are blocked as infected. The rest go through.

So they're still out there. :) -- Freddie Cash fjwcash@gmail.com _______________________________________________ Help us build a comprehensive ClamAV guide: visit http://wiki.clamav.net http://www.clamav.net/support/ml
