How to _completely_ reset Mac Mail to pristine settings
I've been battling Mac Mail now for quite a while, first with Big Sur, and now after the Monterrey upgrade, as well as another fresh wipe and reinstall of Monterrey. Strangely, the problems persist. It is pretty severe, as in the client will not send or receive mail, ever. Oddly, I can add an IMAP/SMTP account and it will act like it usually does and seem fine. But I simply cannot get anything through. I am my own email provider and have three other user agents which all work perfectly. I followed the steps in another post about "resetting Mac Mail" but it didn't work for me.
Is there some way to _completely_ revert Mail to it's virgin state, whether that means blowing away any iCloud bits or what not, I really down't know. I just wish it would work!
