I'm setting up quota for my users, my users have a UID starting on >5000 and GID = 5000, and when I query the quota, for example in IMAP, I get:

Nov 8 14:13:28 fastmail dovecot: imap-login: Login: user=a@a.com, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=18660, secured, session=

Nov 8 14:13:37 fastmail dovecot: imap(a@a.com): Error: net_connect_unix(/var/run/dovecot/dict) failed: Permission denied (euid=5000(<unknown>) egid=5000(<unknown>) missing +r perm: /var/run/dovecot/dict, dir owned by 0:0 mode=0755)

Question is, should I have the GID on the users set to 0, or is there another way to workaround it?

Thanks,
