It's possible that the system that marks the e-mail with the X-Forefront-Antispam-Report: ...;SFV:SPM;... also sends it to the less-reputable-ip-address pool to be sent out, so one would think that basing a filter off of X-Forefront-Antispam-Report *should* be enough. https://www.mail-archive.

But it's not really the same. Not all providers offer free accounts which clearly attracts abusers a lot more than paid accounts. Furthermore, not all providers do this: "Segregation of outbound email traffic: Every outbound message that's sent through the service is scanned for spam. If the messa
