No RFC *obligates* any recipient to honor DMARC *at all*. Nobody has any obligation to check SPF, DKIM or DMARC on incoming mail. All these are *completely optional* and the fact that the sender does publish the approppriate records in DNS and/or DKIM signs their message does not obligate the recipient to check/verify this in any way. You cannot treat "not applying policies at all" as anything bad. Ignoring SPF/DKIM/DMARC is a completely normal behavior. It's just like a B&W monitor ignoring the color signal, but still being compatible with the standards and able to display the image. Or someone using a classical 2G mobile phone to just make a voice call, ignoring the fact that the network can also carry 4G LTE (because he hasn't any need to use it). -- Regards, Jaroslaw Rafa r...@rafa.eu.org -- "In a million years, when kids go to school, they're gonna know: once there was a Hushpuppy, and she lived with her daddy in the Bathtub." _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
