I've got a question that is somewhat similar to this. I've been getting a lot of spam, where the spammers are using my domain in their From: address. Is there any way to force anything coming from one of my domains to authenticate? An IP based solution won't completely work, because we have roaming clients (salesmen) and another office with a dynamic IP.
Mail from mydomain.tld is in my spamassassin whitelist, in order to prevent their legit mail from being stopped, so this spam always has a score of around -95. Or, can anyone think of a better solution?

You should really stick to the vadddomain and qmailadmin. To answer your question, no. People can't telnet into your mail server and spam using your domain outward.
