We're currently using MailHop Relay in conjunction with a MS Exchange server 2003 and an ADSL with fixed IP address. We are now contemplating changing our ISP to a new firm who also provide a fixed IP address. Our MailHop Relay account is set up to deliver to a DynDNS domain name on port 25. As our IP address is fixed, of course, our DynDNS domain consistently points to the same fixed IP address.
We now wish to change to a new ISP. The change over will take three daysover the course of a weekend. I guess the first step in the exercise will be to change the IP address to which our DynDNS name points to the new IP address, even if it is not yet connected to our mail server and then on the Monday morning, once the changeover has been completed change the settings in our router to connect to the new service provider and thus the new fixed ip address.
Can anyone foresee any problems we might encounter? Am I correct in believing that any email messages will be simply stored on the MailHop server until they can be delivered to our Exchange server once it is connected and that email senders will be complete oblivious to the change over?

It sounds like you're all sorted.
You're right in that (assuming you don't receive massive volumes of email over the weekend) the switch should go un-noticed by senders.
