I am having a small problem with Postfix. Everything is now working fine and I think I just need to fine tune it a little bit. I can send and receive mail no problem on my internal network. I can send and receive mail using Squirrelmail from internal and external. I can receive mail externally but cannot send mail externally. It comes up with error 550 cannot relay. Any hints would be much appreciated.
