Shaw → Re: Scan to Email problem resolved

If you we're using an ip instead of fqdn that is your own fault. A simple google search for shaw smtp would have saved you hours of time. Anyone with a technical background knows this. By saying shaw needs to have a status page for smtp is crazy. They need outage status well before an smtp one. You need to do more research before taking on anything technical again.

That is part of the idea with FQDN isn't it?

A server goes down (or IP reused for something else), take it's A record away and the traffic goes elsewhere.
