We've had similar issues being reported in the UK Higher Education 
community. It would appear that AOL's adoption of the SPF standard is 
starting to bite, and it does have the consequence of creating problems 
for forwarded e-mail, as the From: address domain does not match the 
domain of the forwarding e-mail server.


As far as I know there is no solution, except to advise AOL customers 
that they cannot use their AOL mailbox to receive forwarded e-mail. 
Perhaps it would be best to direct their customers to read

http://postmaster.aol.com/      and in particular

As far as I know AOL is the only big adopter of SPF - but it does have 
implications for alumni forwarding if it does become more widely adopted.
