1. SPF records don't prevent anyone from mailing; they merely provide
the recipient more information about how to handle that mailing.
2. AOL _never_ intentionally allowed people to mail directly from
their connections without going through AOL's mailservers.
he'll probably sue them for breaking contract.
And lose. Have you read the contract?
At least in Germany they see "Internet access" and I don't see
anything in the contract that forces me to use their MTAs.
Do you see anything in the contract that requires them to validate
email sent not through their MTAs?
Sometimes I have the impression people talking about all those
