I'm thinking you could also just moderate the entire list for a few days (with "Send= Editor,Hold,Confirm") and eventually he might get tired of the fact that you won't approve his messages, no matter <where> they come from... The kicker is that with all of these freebie e-mail providers (HOTMAIL, BIGFOOT, etc) he could jump to one of them from JUNO, making even freezing all JUNO users out a waste of time. And don't think he isn't that smart :) You could also set * Default-Options= REVIEW in the list header and then it doesn't matter if he unsubs and resubs from another address. Legitimate subscribers could be set NOREVIEW later, after a probation period. Nathan
