Seen Flags per User

[Maurice Kunze]

Hello,

i want to configure seen flags per user for shared public mailboxes in 
dovecot. I have added the INDEVPVT Option to the location parameter in 
the namespace and restarted the services and the server.
Unfortunately nothing changed and there are still global seen flags in 
the configuration. In a post i read that i have to manually add some 
files to the location but this isnt specified in the documentation.

below is the version we use and the config.

dovecot --version
2.3.13 (89f716dc2)

dovecot -n
# 2.3.13 (89f716dc2): /etc/dovecot/dovecot.conf
# Pigeonhole version 0.5.13 (cdd19fe3)
# OS: Linux 5.10.0-17-amd64 x86_64 Debian 11.4 ext4
# Hostname: <SERVERNAME>
