Oh, and as far as the backup mailserver goes, email is relatively self-healing anyway. I say that a backup for kclug is unnecessary. Almost all mail servers will keep trying for five days or so, and if the mailman server is on a machine that's not accepting mail, storing rejected mail on a backup won't really help matters any.
