Does anyone know how I can force everyone that connects to my mailserver (qmail-1.03-r10 ebuild) to use SMTP AUTH (if the mail is going to be relayed)?

Here is my tcp.smtp file:

Have you checked out qmail-smtpd-auth? I don't personally use Qmail (Postfix here), but that looks like it does what you want.

Yep, I've got it compiled in and set up.

I just don't know how to force users to use the AUTH command.

If a domain being sent to isn't listed in RCPTHOSTS in /var/qmail/control it will not be accepted for relaying unless RELAYCLIENT is set in /etc/tcp.smtp OR by the qmail-smtpd-auth patch. One thing to beware of is that smtpd-auth and relaymailfrom patches clash (though there is a merged patch floating around). Its a one line fix, but I don't remember what it is off the top of my head.
Have you seen unexpected relaying, or are you just asking pre-emptively?

I'm just asking preemtively, just to make sure that I dont run an open relay.
