1 - Yes I was able to reproduce with a completely new user. I didn't use your doveadm commands above, but created a new Linux user in group mail, set a password in /etc/dovecot/users, and sent a few emails to that user from another mail account / web mail. My SMTP server is Postfix. Then I used my IDLE client code (which does SELECT CONDSTORE) and a separate netcat connection to make flags changes. Same thing as before: 1) no flags changes flushed to IDLE 2) until the other connection (which changed flags) does a SELECT. The only difference from before - it was enough for netcat to do plain SELECT (i.e. SELECT CONDSTORE was not necessary). I also tried a netcat connection instead of "my IDLE client" and did plain SELECT before going IDLE (i.e. SELECT without CONDSTORE). Same thing: 1) delay 2) flags changes are flushed after the other connection does SELECT. 2 - I switched to Maildir last night - and the problem stopped for same old existing user. So it looks triggered by a combination of mbox + SELECT (CONDSTORE)? 3 - No errors in doveadm log errors 4 - /var/log/mail.err has this Mar 13 09:21:17 kman dovecot: auth: Error: Master requested auth for nonexistent client 29548 (created 0 msecs ago, handshake 0 msecs ago) Mar 13 09:21:18 kman dovecot: imap-login: Error: net_connect_unix(/var/run/dovecot/stats-writer) failed: No such file or directory Probably means nothing - I tried to log in with IMAP before remembering to add my new user to /etc/dovecot/users -- K
