Bad Detection: Outgoing Mail Server Hostname

I use this plugin all the time — it has been great (overall).

I just installed it on a new site and it detected the”Outgoing Mail Server Hostname” completely wrong on a domain.

I checked the DNS from multiple locations but it insists that it should be set to “relay-hosting.secureserver.net” which is completely incorrect. The domain in question isn’t even registered through GoDaddy, let alone pointed there in any way or any record within its DNS zone file.

I will probably have to set it up manually.
But I wanted to make sure I brought this up so it can be looked at and we can figure out what’s going on.
