[Mailman-Users] List posts sent to AOL list subscribers bounce as undeliverable (v. 2.1.20)

I'd say the domain does need to be fixed first. I recently encountered a 
mail server (not AOL) which refused to accept mail from my domain 
because I didn't have an MX record.

As far as I can tell, it is not the individual AOL users who need to 
request whitelisting, but rather, the server sending mail on behalf of 
the list. Remember, all the AOL users are doing is possibly sending some 
messages if they participate on the list, and they're also receiving 
list traffic. Since the issue is with AOL users receiving mail, not 
sending mail, it's the mail server that needs to be whitelisted, but 
before doing that I'd make sure all the DNS stuff is in order.
