fwiw, ietf+censored currently has the following set of filters in taboo_body:
/^Antigen for Exchange found/
/^Virus Notification: A virus has been detected/
/^Antivirus Utility for Exchange found .* infected/
/^Content-Type: application\/x-msdownload/i
the last one is ONLY included because I got so very tired of scanning the
virus notifications trapped by the first 3 lines (23 caught at last count).
It is my arbitrariness, not a virus-scanning service.
