Actually, in 2.1.18+ dmarc_moderation_action is more often than not preferable to from_is_list. See <https://wiki.list.org/x/17891458> for other possible mitigations some of which apply to older Mailman versions. > I need to update desperately.

Actually, the current Microsoft warning is issued when the From: and To: (or Cc:) addresses are the same. This affects anonymous_list as well as DMARC mitigations. It seems the (partial) way around all of this is to apply DMARC mitigations when necessary or always (via dmarc_moderation_action or from_is_list) and to set personalize to Full personalization so that To: is the recipient, not the list. Without better knowledge of Microsoft's rule, it's difficult to know how to deal with it, and I'm sure Microsoft would consider such information to be proprietary. > In that light, should I just be moving to anonymous_list anyway?

You might consider anonymous_list as a DMARC mitigation in pre-2.1.16 only, but better to upgrade. -- Mark Sapiro <[email protected]> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
