As far as I know, SPF was never meant as an anti-spam measure. SPF protects against *impersonation*, ie. someone else sending mail as your domain. But majority of spam is not connected with impersonation. Spammers send mail from their own domains, or from ad-hoc created accounts on publicly available mail services like Gmail. They don't use fake addresses at someone else's domain. There was some visible percentage of spams that used such fake addresses about 10 or more years ago, and this probably vanished since introduction of SPF - but this was never a significant percentage. Impersonation is more often used in malware attacks (eg. phishing) than in spam. But there are other methods to detect and prevent malware. -- 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
