Sympa lets you use an external antivirus solution to check incoming mails.
In this case you must set the antivirus_path and
antivirus_args configuration parameters
(see 6.13, page .
Sympa is already compatible with McAfee/uvscan, Fsecure/fsav, Sophos, AVP, Trend Micro/VirusWall and Clam Antivirus.
For each mail received, Sympa extracts its MIME parts in the /usr/local/sympa-os/spool/tmp/antivirus directory and
then calls the antivirus software to check them.
When a virus is detected, Sympa looks for the virus name in the virus scanner STDOUT and sends a
your_infected_msg.tt2 warning to the sender of the mail.
The mail is saved as 'bad' and the working directory is deleted (except if Sympa is running in debug mode).
