> lists were subjected to a sort of a "flood attack" It wasn't necessarily a malicious attack. I've seen this happen a few times, and the perpetrators were usually just clueless and often suffered more inconvenience as they caused me. What you did is as close to "correct" as I think you can get. (if anyone has a better plan, I'd love to hear- now that I think about it, using sendmail's access features might be more appropriate) I usually add a step of emailing the admin of the server in question, just to be safe. What I think you might be seeing is a typical loop scenario, caused by brain-dead autoresponders or mail servers. Someone subs to a list on your server, and when majordomo sends them something it generates a response (either a bounce, or a "we got your mail" message) that is (probably improperly) sent to 'majordomo' - which of course majordomo doesn't understand, so it thoughtfully sends them the 'help' message. The help message then causes the generation of another response. And so on... -=Jim=- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
