Subscribers may have spam filtering, but I wouldn't rely on it totally -- for one thing, spam should be kept out of any dalnet-src archives.. I prefer to be able to whitelist mailing list messages. If users of services like 'yahoo' actually got bad messages, and chose 'report spam', it could hurt dal.net's reputation in those services (as dal.net mail servers relayed the spam) I would think postings from subscribers and possibly other known-good addresses should be made to almost always pass straight through. Whereas attempts by unknown non-subscribers to post should either require approval or still be filtered, with the sender receiving an error message indicating they need to subscribe. If spam from subscribers was a problem, well: I know some mailing list management software permits 'new subscribers' (or specific subscribers) to be moderated, and I would suggest looking into that option, Long-term discussion participants would have already gone through that one-time moderation for first post and already been made unmoderated. But some bot subscribing just to spam would run into problems. -- -Mysid
