Here is a iPhone pic of the email setup window and the failure email message. (easier than taking a screenshot). And yes a Yahoo account is the same as Rogers. They are affiliated.
And the only thing I have found in the log is an “error loading gns endpoint settings.” I see nothing related to the attempt to send an email, which I guess makes sense if it has no settings as to where to send it. I don’t know why it hasn’t loaded the endpoint settings. BTW, I do have the iPhone gns app communicating with the laptop using gns. I had downloaded gns, not knowing it was already in SG Pro, and went through their instructions to test the communications. I have since deleted the independent version on the advice of Jaime at GNS, and will use the version in SG Pro.
