Just exempt Microsft servers from SPF checking. I don't know what mail server software are you using on your server, but for example with Postfix you can configure all the checks and verifications any way you want at any stage of SMTP transaction. So it should be quite simple to exempt Microsoft servers from SPF checking only while not completely "whitelisting" them (I understand by "whitelisting" you mean exempt from any checking and unconditionally accept the message). BTW, SPF is not and never was meant as an anti-spam measure, and has virtually nothing in common with spam checking. The most notorious and active spammers have usually SPF, DKIM and DMARC configured perfectly fine. -- Regards, Jaroslaw Rafa [email protected] -- "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 [email protected] https://list.mailop.org/listinfo/mailop
