dovecot - Sep 2019 - keywords lost when moving a message in a folder

Hi,

I migrate my dovecot server from Debian 9 to Debian 10 (Dovecot 2.3.4.1),
since when I move a message in a folder, keywords systematically disappear.
I'm using Thunderbird 60.8.
Would an option have escaped me? or is there a bug on this version of
dovecot?

Hi!

This is fixed in 2.3.7 forward, you can find packages from
repo.dovecot.org, or you can try opening a bug in debian bugtracker.
