Your suggestion has merit. It does however miss the point of why I do what I do. My MX is for the domain that I have registered to myself. I don't want "dyndns" in the middle somwhere. I already pay folks for the privelege of using their machine to host my website, so why not also let them host my CNAME and MX?

The good news is the DHCP assigned address changes infrequently enough that this approach that I'm using isn't a major PITA. If it ever became such I'd re-review my options and possibly implement something along the lines of what you suggest. When I first started hosting my own mailserver and farming out my MX DNS entry DynDNS was not an ooption.

In fact, the incidence of my IP address changing happens so infrequently that I've even considered adding to this script (and it's predecessor which wasn't as nice as this one) logic to automatically create the trouble ticket with my hosting provider for them to update the DNS entry.

I'm just waiting for the day when T1 lines become "affordable" and I can host my whole domain myself. Yeah... right... dream on...
