Solve the problem simply. Blacklist everybody who uses such an asinine annoying system. I do that up in my ~/.procmailrc file. If a person wants to look like a spammer fishing for addresses I'll be happy to guarantee that I never see email from that person again. It keeps my blood pressure down to safe levels. Challenge Response to a mailing list is stupid. It means I'd have to answer thousands of challenges each time I posted a message to a new mailing list. It's such a rude thing to do I figure I want nothing to do with the individual who is so unthinking as to do this.
