Hlep with my maillogs, please?
Does it look to you like this black-hat succeeded in using me as a relay? At the bottom, that attempt after a failure, using 24.98.6.7 as an address? That really IS my IP, and did sendmail think this was local mail, and alright to handle? I see he didn't send anything, but can he, at a later time? Thanks.
