[Dovecot] Dovecot - AllowGroups option

[Jacob Neergaard Pedersen]

Hi,
I'm trying to control access to different services on an Debian server using /etc/group. So that a user I create for FTP usage doesn't fill up my server with IMAP folders or samba garbage.

Services like proftpd have:
"AllowGroup ftpgroup"


sshd have
"AllowGroups sshgroup"


And samba have
"valid users = @smbgroup"


But I can't find the correct option in Dovecot (/etc/dovecot/dovecot.conf)

Do anyone have the magic option or a workaround thats doesn't envolve maintaining seperate user databases and password? (I know its needed for samba but besides that)
