I had an issue posting to the AOLServer list since they introduced their reverse lookup. The lists mailserver bounced it with a 450 error because the domain I'm posting from isn't holding the mx record for the e-mail address I'm using (manning.net is a Netidentity postbox).
Might be the same issue for you. I solved it by posting through Netidentity's SMTP server but its a pain in the behind to have to remember to switch accounts before posting.
