Dovecot Dict permission error

[kafmil]

I found an issue that I am struggling to find an answer for. I am getting this error:

Jun 12 10:03:48 vds1 dovecot: imap(webmaster@<mydomainname>.com.au): 
Error: net_connect_unix(/var/run/dovecot/dict) failed: Permission denied (euid=97(dovecot) egid=89(postfix)
 missing +r perm: /var/run/dovecot/dict, euid is not dir owner)
Jun 12 10:03:48 vds1 dovecot: imap(webmaster@<mydomainname>.com.au): 
Error: Internal quota calculation error

I can chown the file /var/run/dovecot/dict to dovecot, however when I restart dovecot, it reverts back to root as the owner. If I don't restart dovecot, everything works well, I am guessing this is still a config issue here. I am chowning and not restarting for now, but will keep looking for a proper solution.

Any ideas out there?
