Hi, Qmail does not check if a user @ valid domain exist ( there are patches to look for a valid user first at smtp level ). When, for example a spammer, tries to deliver mail to a non existing user on your system it accepts the message. Then looks if that user exists and if not it bounces the mail back to the sender.
Then you see those qmail-remote childs. Take a look at the content of the messages in your queue. That will explain a lot.

I would like suggestions on keeping this in check. I use qmail-scanner. I use qmail, with smtp auth, so I can't be used as a spam relay, unless someone has cracked one of my mail account passwords. here is an example: 7556 ?
