In an attempt to secure my qmail installation I am at a lost on how to make qmail not allow someone outside my network from spooling email from my domain to someone else.

For example I could telnet into qmail and create an email that looks like someone from domain and send it anywhere. This of course is a great social engineering technique.

The question becomes, is it possible to have qmail reject such messages that are coming from outside the network. No one outside the network should ever send an email from our domain. Only emails from our domain should be initiated withine our network.
