18. Antivirus

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 5.13, 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 `/home/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).
