Once, a long long time ago, I received one from 'hotmail' as well. Only the sender was stupid enough to use their own hotmail account *rolls eyes* It was a name that would never be used by- ah, well by the real hotmail.
This one though had an something@aa.com address *glares at owner of the account*. I really don't know how they managed to get that address.

It would be splendid if Hotmail has such an option as well.
*makes ready for combat* Then we can hunt down the culprit *BB Bryan glare*
...
Or let them (Hotmail) take care of it. *nods* They have lawyers.
