If I understood your problem correctly, the problem are spoofed senders. I think you should look into SPF and similar techniques and do not accept mail from your domains which do not come from one of your mail servers. This is imho more a MTA configuration thing. > As I said, I've tried to accomplish this using meta rules in SA, but > have not had any (good) luck... I think, a SA rule should work, too. Can you explain your problems with that in more detail please? (Although I think SPF is the better way to approach your problem.) -- Felix ------------------------------------------------------- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
