It seems difficult to test a negative (what? it doesn't bounce after 10 days? I guess it'll never bounce). I prefer Mailman's positive test approach of sending several notices and requiring an explicit confirmation for reinstatement. > This is what ezmlm does.

Bounce messages triggered by content-based filters are evil and must be eradicated. When SoBig.F came out, we had effective filters in place within a day or so for the specific viruses themselves. What absolutely killed us was all the "helpful" bounces that the zillions of content filters send when they block such a message. And even if you think /that's/ okay, not putting limits on those block messages is still evil. -Barry _______________________________________________ Mailman-Developers mailing list [EMAIL PROTECTED] http://mail.python.org/mailman/listinfo/mailman-developers
