So I guess someone is using my e-mail address for sending spam, and I guess I'm not the only one, The reason for spammers to use a valid e-mail address is quite clear, a lot of anti-spam systems perform this kind of check, to see if the sender's address is real and has good "reputation"

Damn both the spammers and the broken mail servers that accept the mail 
first and then bounce it back to the forged "sender", thus being a 
secondary source of spam.

The receiving mail system upon getting mail for an unknown user, mailbox 
full, or anti-spam detection should reject the mail immediately, not 
accept it and then later attempt to bounce it back to the purported sender.

Don't even get me started on "out of office" autoresponders.
