Inbox has stopped showing new messages. I see the count increase, but no new messages show. For mail that I've set filters for, I can see those in the folders they are moved to. What I've tried: - Maybe too much mail? (I keep a lot, going back 9 years) I've emptied most of the trash, and moved old msgs from inbox to archive folders. - Compacted mailboxes - Shut down TBird, deleted global-messages-db.sqlite then restarted to rebuild index. I can access my mail through the web on the mail server, so can see the mail that is not showing up in inbox.
