Recovered Messages folders in Mail
I am on HighSierra and in Mail there are folders created in my Mail/On my Mac area, one for each of my 3 email addresses. Are these duplicate emails [I use IMAP for all 3 accounts] so I can just delete the messages and mail boxes, or do I have to move these emails to the inboxes and deal with them as needed ??
