aol rejects mailing lists?

Hey guys, I've noticed on one of the mailing lists that I'm running that AOL has just started bouncing email (like literally a few minutes ago) sent to subscribers of the list. Email does get delivered properly when sent directly to the subscribers. If the mail gets delivered thru the list, it's rejected with a 550 MAILBOX NOT FOUND which is bogus. Anyone encountered this before? How do I get them to stop this nonsense? Help?
