We see more and more spam whith :

- Real address for reply-to (not spammer adress of course ;-)
- Reply-to based on existant domain : rand_string at domain.tld


AP> (aren't they anyway if a spammer uses their addresses ?)

How do you feel if spammer use your adress in reply-to : innocent or
victim ? ;-)

>> And what append if sender use the same system ?  you send a

AP> the confirmation request is unlikely to be detected as spam and since no
AP> reply is send out when something is received at the confirmation account
AP> no such loop will ever happen.

Ok
