On my old machine (2018 Intel Mac mini) the On My Mac section of my Mail.app (which contains a load of folders organised by rules - client stuff, personal interest stuff - as well as its own junk folder), if my spam catching rules threw a false positive I would hit Move To Inbox and it would move it to my pop account, because that was the "owner" of On My Mac.
My new machine (M2 Pro mini) was set up as a new device, not via Time Machine (long story), I have the same rules and same folders and manually moved the mailbox content over (fun!). All seemed good. However, if I noticed that if I used Move To Inbox on On My Mac's junk box, false positives vanished.
After much exploration (including with Apple second level support) the problem was IDed as being ownership of On May Mac. It is "owned" by my iCloud account, so Move To Inbox sends it to the iCloud inbox - and as soon as the IMAP syncs, it gets deleted because the mail is not an iCloud email and does not exist on the server. (Sidenote: Apple's engineers have misunderstood this and tried to blame my Gmail account, which is an entirely innocent bystander - net result, more test hoops to jump through).
The problem: no matter how many times I try, I cannot change the ownership of On My Mac. As soon as I close the Account Info box, it reverts to iCloud. The only ways the change sticks is if I disable all mailboxes except my pop - and as soon as I re-enable, it reverts to iCloud again.
As I say, on my old machine On My Mac is "owned" by my pop account and never had this issue. So does anyone have some secret sauce that will change On My Mac's ownership and have it stick (I've tweaked the spam rules to bypass it but if I, say, accidentally hit Move to Inbox on ANY On My Mac folder the same vanishing act happens)?
For clarity: mailboxes are personal pop account, business pop account, iCloud, Gmail (both IMAP, obv) and an unused BTInternet imap account.
It is *only* when moving stuff from On My Mac's folders the issue occurs. All other Junk boxes behave as expected.
