dsync: Keywords not being replicated

[Karsten Heiken]

I just noticed that some IMAP keywords are not being replicated through dsync backup/sync using Dovecot 2.2.24 from Debian backports:

On the master server everything looks fine:

RECORD: seq=3, uid=44731, flags=0x09 (Seen Answered)
  - ext 0 keywords  :            (0900)                     <-- 0900
  - ext 1 modseq    :     701695 (ffb40a0000000000)
  - ext 3 cache     :       3948 (6c0f0000)
  - ext 4 sort-s    :          0 (00000000)


On Replica:

  RECORD: seq=3, uid=44731, flags=0x09 (Seen Answered)
  - ext 0 keywords  :            (0000)                     <-- 0000
  - ext 1 modseq    :     701695 (ffb40a0000000000)
  - ext 3 cache     :       3948 (6c0f0000)


In this case the "forwarded" keyword is gone. Thunderbird no longer displays the message as having been forwarded.
The command I used was:

> doveadm sync -u myuser -l 60 -N tcp:replica:24245

My config is attached.


It looks like there are other users also having the same problem: http://dovecot.org/list/dovecot/2016-January/102951.html


Thanks,
Karsten
