Re: Overcoming IP changes from Cable ISP

This can easily be overcome by using AUTH SMTP - I have many sites sending
to ISP Smarthosts in this way - Agree if you use DNS to route the messages
this will be an issue - however this has obviously not been an issue so far.

Why use DNS to route when you can offload that work to your ISP!
