Hi Al - no I am not, this was a single email sent only to me. Possibly a misconfiguration of the header on the sender’s part, but eM still shouldn’t pick a random contact from my list and display their details when I mouse hover-over the sender’s email address.
To be fair I trash all email coming “on behalf of” for safety reason.
If the email is “on behalf of” one of your contact most likely his contact info will show up but if you dont recognize the TRUE email address that sent this mail on behalf of your contact I wouldn’t open it they may be spoofing his address to spread malware.
