It's a good idea in general to prohibit outside posts. But this won't stop the bogus worm-containing messages being sent out with fake "From: " addresses which are addressed as coming from the list, you, or even me. These worms gather email addresses from received emails, inboxes, etc, etc, and use valid "From: " addresses to masquerade as anyone they want.
True, but some worms use the e-mail address list of the victim and use those addresses as "from-address". Therefore keeping unsubscribed users out of the list would still help keeping the "trash" level of the list low.
