Thanks, Odhiambo. I was about to disable message receipt as I usually do after getting answers, when I got an email to my Gmail account that was possibly a phishing attempt just after I had asked about authentication. Coincidence or something I should be worried about? I'll just delete the message soon, but below is the suspect email. I can probably get the headers if anyone is interested.
