Bellsouth.net, Smart Hosts, and Exchange 2003 on SBS 2003

Ok, so I've had my SBS 2003 running in my home. I am running a small business, but my DSL connection is a Bellsouth.net DSL residential connection and they block port 25 both inbound and outbound. I've scooted around this over the last 9 months by using ZoneEdit to Forward my company email to my IP address on port 2525. My outbound email hasn't really been an issue since it was routing via DNS.

Ok, it really has been a problem. I haven't been able to send to AOL. Not that I care (I really hate AOL, but my wife has a company email account and needs to send from our domain to AOL). As any wise married man knows: it's now imperative that I solve this problem. Well, I didn't. I waited (for around 9 months or so ---- Besides, I didn't say _I_ was a wise married man!).

Within the last week, most of my outbound emails have been kicking back with an NDR. I started using the Smart Host and configuring it to use my bellsouth.net settings, but could NEVER get this to work. I finally ended up using the DYNDNS.com's Outbound Mailhop service. It worked like a charm. Don't forget that after you run the Internet Email and Setup Wizard, you'll need to open up Exchange System manager and do a bit more work...
