Your thread seems to me to fit the list's mandate. I don't have a strong opinion as to the alert Gmail provides when a message has the From header matching the To header, though it seems to me most of the time it would result in an SPF failure (whether soft or hard) and so be problematic. I've done this a few times but always between machines that would pass SPF checks. I've no certain idea as to why Google wouldn't provide an alert when the From header names some other Gmail address yet didn't originate from a Google server, apart from guessing that they have some bugs or as yet unresolved edge cases they're considering. /mark _______________________________________________ mailop mailing list mailop@mailop.org https://chilli.nosignal.org/cgi-bin/mailman/listinfo/mailop
