Hello I have noticed that when per-user \Seen flag is configured dovecot do not respond properly to 'store' command. eg.:
=============== 42 uid store 6 +Flags (\Seen) 42 OK Store completed (0.001 + 0.000 secs). 43 IDLE
idling DONE 43 OK Idle completed (3.204 + 3.203 + 3.203 secs).
Thunderbird is confused by this and read emails turns into unread after a while. When global flag is stored dovecot responds as it should, I think:
=============== 32 uid store 3 -Flags (\Flagged)
- 2 FETCH (UID 3 FLAGS ()) 32 OK Store completed (0.002 + 0.000 + 0.001 secs). 33 IDLE
idling DONE 33 OK Idle completed (5.362 + 5.362 + 5.361 secs).
When per-user \Seen flag is not configured:
=============== 25 uid store 6 +Flags (\Seen)
- 4 FETCH (UID 6 FLAGS (\Seen)) 25 OK Store completed (0.002 + 0.000 + 0.001 secs). 26 IDLE
- idling
OK Still here DONE 26 OK Idle completed (65.076 + 65.076 + 65.076 secs).
