[Mailman-Users] Virus Scanning

I simply put a 40,000 character limit on message size. It eliminates every virus
I'm aware of, and also blocks someone from accidentally replying to a message
and helpfully including some monster file with the answer. (I used to see that
on one list, discussing an illustration program, where one helpful person would
offer to look at the problem file and the original user would then attach an 8MB
map to the whole list.)

Virus scanners are an option, but they cost money. I run Mailman on a dedicated
machine and run Kaspersky on my main mail machine.
