I think I see the problem. After reading my latest message on here and looking at the headers of the message it seems that postfix is sending out the mail directly without using the smtp-authentication I setup. In short, this message when it goes out to postfix to send out is going directly to braille.uwo.ca and not to my hosting service which is mail.asmodean.net. This would make sense because if smartgroups blocks consumer ip address ranges or something similar then it would reject my mail. If this is the case it's now a question of how to get all outgoing mail to use the smarthost I setup with either exim or with postfix. I had this working fine with exim 3.x but since installing FC3 it has exim 4.x and I'm not as familiar with it. I followed a howto I found on google to setup smtp-auth using postfix but it does not seem to work either.
