I'll bet you spammers just hijacked that email & they didn't use your sever as
the relay. Have your friend look at the email header & see where the
email was actually relayed from - prolly not you.
Having had my personal email hijacked as well as bogus usernames from my
various mail domains hijacked it's ugly & there's nothing you can do but
get ready for a LOT of bounces.
