Hi,
We run the open source ClamAV on our Linux servers. It scans incoming and outgoing emails. You can see if it's working by looking at the email headers and looking for the strings:
X-Virus-Scanned: ClamAV version 0.88, clamav-milter version 0.88 on localhost
X-Virus-Status: Clean
X-Antivirus-Scanner: Clean mail though you should still use an Antivirus
Of course, the version number will change as newer ones are released.
