How are you receiving these notifications from AOL? As normal bounces 
sent to the envelope sender address?

Other Mailman lists I'm on utilize Variable Envelope Return Paths 
(VERP)[1] (as someone else mentioned), so I assume it is something 
Mailman supports.

VERP is a technique where each message is sent using a unique envelope 
sender address that can be used to identify who the original recipient 
was when a bounce occurs. There is no need to modify the RFC822 headers.

Contact me off-list if you'd like help figuring this out.
