Sure. As a matter of fact, I did run an SMTP server on my domain with dynamic IPs about 8 years ago. I didn't run into any problems probably due to several factors. 1. My system rarely disconnected but when it did it seems the lease lifetime was set to a high value and I almost always got the same IP upon reconnection. 2. Even when I didn't get the same IP the demographics were such that 99% of the time the system that got my IP was a PC running windows and no SMTP service. > Long ago, I decided that trying to be my own SMTP server was too much > trouble to bother with.

For a small set up there really is no value to having a second server and MX record. I would only put up a secondary server if I had multiple internet connections into the enterprise. If my single server dies I can live without email for the time it takes me to fix the problem and I'd be too busy fixing it to read email even if I had a backup. :-) My DNS provider offers to act as a backup email server free of charge but I've never taken them up on the offer. > I settled for running my own server for our outgoing mail, and let my > domain's hosting equipment handling my incoming mail. > I'll admit it, I'm a control freak. :-) FWIW, I've given up trying to follow the rest of this thread....seems nobody knows how to trim. :-) -- Politics are almost as exciting as war, and quite as dangerous.
