I haven't done much list administration for years, and I don't know mailman. But I wonder whether a semi-effective filter for our list would be to check the message body for the names of nmh utilities (scan, repl, etc.) as well as the names of the source files (foo.c, etc.). If none of those words are in the message, treat it as suspect. When the moderator/owner notices a "suspect" message that isn't bad, check and maybe update the "whitelist".
No flames please. Like I say, I'm clueless. This is just an idea. Jerry _______________________________________________ Nmh-workers mailing list Nmh-workers@nongnu.org http://lists.nongnu.org/mailman/listinfo/nmh-workers
