What I don't understand is how can a linux mailing list (a list DEDICATED to linux) can be effected by a WINDOWS virus. First, any virus sent to the list should be ineffective, because everyone should be running linux right? Second, a virus should not be sent to the list because of the first point. How about a procmail receipe like this: :0B * ^X-Mailer: Microsoft.* { :0 /dev/null } -- Bob Tanner <tanner at real-time.com> | Phone : (952)943-8700 http://www.mn-linux.org | Fax : (952)943-8500 Key fingerprint = 6C E9 51 4F D5 3E 4C 66 62 A9 10 E5 35 85 39 D9
