Interpretation of SPF check results is and always was a decision of the recipient. The SPF RFC (RFC 7208) says clearly: "Disposition of SPF fail messages is a matter of local policy." You can use SPF check results to influence spam score of the message, and it is usually used this way. -- 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
