mailbox_idle_check_interval = 1 secs did not help Here is an interesting case - Let's say I have my IDLE connection. - Connection "A" - an email app where I set or clear \Flagged on two messages. The IDLE connection is silent (no unsolicited notifications about these flags). - Connection "B" - an email app where I do a refresh - it does a SELECT (CONDSTORE) followed by FETCH UID FLAGS CHANGEDSINCE (because it sees that there are only flags changes). ---> the IDLE connection is notified about flags changes immediately right as Connection "B" is pulling its changes. I tried a direct network connection (netcat) instead of Connection "B" and the actual trigger is SELECT (CONDSTORE). - Start up IDLE connection - Use Connection "A" to make flags changes ( IDLE connection is silent ) - Use a netcat connection to SELECT (CONDSTORE) Dovecot flushes flags to the IDLE connection immediately - Doing SELECT (without CONDSTORE) does not Looks like some sort of bug in Dovecot related to CONDSTORE? This can probably be reproduced with several direct network connections using netcat / openssl s_client - and CONDSTORE seems to be an important part of the scenario. Ideas? -- K
