Recently spam checking stopped to be enough to prevent my mailbox to grow to incredible sizes, so I had to look for some possibility to block viruses and other malware. The obvious choice went to open source anti-virus Clamav.
Setting up was pretty easy, especially when there are tons of howtos on the net (e.g. Installing and configuring Exim 4 on Debian). All I had to do was to install Clamav and configure Exim to talk to it and reject unwanted stuff.
And what are results? Quite impressive - 154860 caught viruses in last 24 hours.I wonder that lots of them were also caught by SpamAssassin, because I definitely didn't receive that much malware in a day.
