Hello,
I'm experiencing slow flags changes over IMAP IDLE:
- If I start an IDLE session / command
- Change the flags of some messages via another email app
- Dovecot can take a minute or more to notify the IDLE connection about flags changes
If I use another email app to add or remove a message, Dovecot sends that (EXISTS / EXPUNGE) instantly and also flushes the (so far delayed) flags changes. So it does "know" already.
The system is Debian Testing, 64 bit, file system is ext4.
Dovecot is 2.3.4.1 (f79e8e7e4) - I believe from Debian repos (I had Dovecot's own repo added at some point, disabled now).
My mail is stored under ~/mail/.imap (not sure what this format is called), I mean not "single file mbox".
I have not changed any IDLE related config settings:
doveconf | grep -i idle default_idle_kill = 1 mins director_ping_idle_timeout = 30 secs imap_idle_notify_interval = 2 mins imapc_max_idle_time = 29 mins mailbox_idle_check_interval = 30 secs
What can I do to make Dovecot notify IDLE clients about flags changes - more quickly? Preferably near-instant?
Can you send doveconf -n?
