Using the two-pane entry form, the response I get is that smtp-5[at]widopenwest.com has no IP address, and is discarded as fake. A subsequent message says my e-mail addy appears to traverse more than one domain, and I have to configure them all individually and in order (which is what I thought I was trying to do).
Technically, it's not that there isn't an IP address .... it's actually the header data that's provided by these servers that's causing the issue, which is based on configuration settings in use ....
You didn't bother to show anything here, so I'll reach back to your Topic starting post that Tracking URL shows the header line details as;
Received: from smtp-3.wideopenwest.com (smtp-3.wideopenwest.com [10.75.2.3])
which goes back to being an internal IP address, therefore non-routable
On the other hand ....

and yet, we see the same data for

I'm sure that there's no association, but .... after years of removing 'new net' crap installed by several malware/spyware things floating around the net .. the New.net name for this ISP/Host/place sure got my attention quick .....
