Thanks Omar_A1
I have both “All Mail” and “Trash”, and my current setting for deleted mail is Trash.
I have Comcast as my ISP and their email is delivered to my inbox as well as my Gmail email.
I have gone to Comcast Mail on the web, and have approximately 15 items in my inbox while showing 104 unread right now in my inbox. At most 10 are really new. A few are flagged for review.
MOST repopulated emails are from Comcast, because it is default for our Amazon account, which we use a lot, so most repopulated emails are from Amazon, but not all.
I wish Apple would have a “select all” during editing a mailbox. Then I could read the new; filter by unread; then delete the rest, rather than needing to select eash unread, and deleting individually.
As per my existing settings on my iPhone: all deleted email go to trash, and are deleted there after one week, and deleted from servers also after one week of being read.
Any suggestions?
