We are running Dovecot Version 2.3.8 (9df20d2db) (from the CentOS 8 repos). Twice in the last week, I've encountered an issue where my Mutt imap client logs into our imap server and has 0 new messages (when I know that there are a lot of new messages waiting on me).

Both times, I've had to shut down my mail client, and then run: doveadm -Dv force-resync -u <username> INBOX

After which, I reopen Mutt and all of my new emails appear in the inbox of my mail client.

Running the force-resync shows no problems. Furthermore, "doveadm log errors" shows no errors on my account and there is nothing in the logs showing that anything is corrupted for me.

Yet, the force-resync is fixing a problem that I can't locate. Where should I be looking (or how should I update my logging) so that I can find out the source of the problem that is causing my repeated inbox problems?

Thanks! Bryan Walton

Can you turn on mail_debug=yes, and provide output of doveconf -n and logs from mail delivery and when you open the mailbox.
