Below is the bounce notice received. It looks like "Excessive or fatal bounces" is the culprit. Our threshold is set to 5.0. Once the bounce threshold score is reached it checks "nomail" next to the account and disables it. You know all this of course.
However, it's not exactly logical that all the icloud and mac email accounts have excessive bounces at once. Or, the hotmail and live accounts for that matter. I went back through the EMWD tickets. 1. (2019)15 hotmail accounts blocked -- Brian updated the SPF and we put it in our DNS records. 2. Hotmail accounts blocked -- (after Brian) updated DKIM, suggested if that didn't work to get our members to "whitelist" our emails 3. Hotmail accounts blocked -- EMWD says Microsoft rejecting dedicated mail from our IP, opened escalation request; Microsoft "conditionally mitigates." 4. 4 months later -- same thing 5. 4 months later -- same thing 6. Uniserve emails blocked -- EMWD said: "Looking at the logs, I see that the list is accepting messages from Hotmail/Outlook addresses. However, Microsoft is bouncing messages from the list sent to those addresses - so although other list members are receiving it, they wouldn't see their own messages coming through the list." 7. (2024) icloud and mac emails blocked -- prior to this we went to a new host, EMWD updated DKIM and we had the new host company put it in the DNS records.
