Here's how this works.
Many (nearly all) primary SMTP servers on the Internet will not forward your email. The reason for this is because your ip belongs to an ISP (this means your IP is a client IP on the ISPs net).
Well, one day, many moons ago a bunch of very intelligent folks got together and figured that letting people run their own mailservers was a goot way to propagate spam. So they put together a database of (among other things) ISP-Customer IPs.
This is where it gets good. You see, now that you are part of the crowd, ALL of those SMTP servers on the net will see your server as an email source and drop your stuff on the floor. Pretty cool huh?

no, I have a gentoo box and a windows box behind a router, and I don't want anything to do with my ISP's mail. I just mentioned the router and windows box and all that good stuff to see if 192.168.1.0/24 was right, because I don't really know how CIDR works. I just fired up mutt from my gentoo box, tried to send an email, and postfix gave me a bunch of connection timed out to smtp.freeshell.org crap. I can recieve email just fine, I'll email [EMAIL PROTECTED], and I log in and go into mutt and voila it is there, but I can't send anything.
