We make it easy for our users to see any errors their ESPs are sending back to us when we try to deliver email. That helps, because they can take it upon themselves to address any delivery issues. I see. If possible, I'd like to learn a bit more of your process(es) how you automagically forward bounces, suspension and unsubscription notifications to the respective user that otherwise would only reach the list owner by default.

Certainly you aren't meaning the spam going *out* of Google servers, and in particular from their own mailing lists at Google Groups. It has been noted here multiple times as a major source of spam. -- 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

Not being inclusive, ESP wise, would be a non-starter. For the most part, in my experience, the largest ESPs are very good. Gmail is the best, both for delivery as well as keeping messages out of spam. But Yahoo is very good as well (and Lili @ Yahoo is great to deal with). Apple iCloud is also good, although their bounce reasons are very opaque. Microsoft/Hotmail, for the most part, is decent, although we'll sometimes see throttling and it can be very difficult to find someone there to address it. We make it easy for our users to see any errors their ESPs are sending back to us when we try to deliver email. That helps, because they can take it upon themselves to address any delivery issues.
