Susan,

As I understand the service, it will redirect Internet traffic to the SBS ISP IP address only. We have used no-ip.org in the past.

The service is purely a DNS for dynamic IPs redirection service.

To get "store and hold" a service like ExchangeDefender would be required.

I do not know of any ISPs at this point doing a reputation services like setup with their e-mail servers at this point.

As an FYI: Most ISPs in Canada will NOT allow SMTP traffic on non "Server" class service plans anymore. They also kill HTTP, HTTPS, and PPTP, and other "server service" in-bound ports. SMTP outbound for anywhere besides their own servers is also being killed off bit by bit.

So, in Canada at least, the DDNS service is a moot point as far as dynamic IPs are concerned. It will work with the static IP setup providing a DIY with a relatively bulletproof not needing to learn DNS setup.
