My Apple Mail has become somewhat problematic. I run four mail accounts, including one Gmail. All are IMAP accounts.
Beginning with my upg to BigSur from Mojave the world ain’t anymore as it used to be.
under ‘On my Mac’ I have five BIN (Trash in the US), two JUNK, one DRAFT, one SENT that don’t belong there. When I try to delete one of the BINs, I get an alarming message: " Delete the mailbox “email@example.com”?** with a warning “Deleting a mailbox permanently removes it and any messages it contains. This action cannot be undone.”
Trying to delete the SENT it tells me " Delete the mailbox “On My Mac”?, Well there ain’t such thing as a mailbox by that name.
The other day all my signatures disappeared, the file that contains them is still there.
I tried to archive all local emails with EagleFiler, but its concept doesn’t do it for me. Too much renaming required.
What is my best plan for a complete overhaul/reset/start from scratch of Apple MAIL?
Suggestions welcome. Thanks.
