Apple Mail keeps moving a sent email from Sent folder to Inbox in Ventura
Since upgrading to Ventura, Apple Mail has starting moving a couple of my sent emails from the Sent folder into my Inbox on my M1 iMac. It has happened twice. The first time it happened, the sent email showed in both my Sent folder and in my Inbox. If I moved the one in my Inbox to the Sent folder, the Sent folder would not show a duplicate, and as soon as I revisited the Inbox, that single sent email would reappear in my Inbox. I finally deleted that email because it was an annoyance.
It is now happening with another sent email. In my Inbox, I happen to display the Mailbox folder, and in the Inbox, that email show the Sent folder in the Mailbox column.
