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 4.12, page .
Sympa is already compatible with McAfee/uvscan, Fsecure/fsav and Trend Micro/VirusWall.
For each mail received, Sympa deposits its component parts in the ~sympa/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.tpl 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).
