All the ones I'm aware of are ones that basically follow the gameplan laid out in RFC 6449. There are mailbox providers out there that provide insight into what percentage of mail from a given source was classified as spam, such as Microsoft's SNDS program and Google's Postmaster Tools, but I've never understood those to be feedback loops, per se, as they didn't and don't tell you which specific messages were judged to be spam by a recipient or other entity. -- *Todd Herr * | Technical Director, Standards & Ecosystem *e:* todd.h...@valimail.com *p:* 703-220-4153 *m:* 703.220.4153 This email and all data transmitted with it contains confidential and/or proprietary information intended solely for the use of individual(s) authorized to receive it.
