I'ld try to set up the managesieve (for RoundCube) - the sieve is works as well with dovecot (I mean my filters works perfectly).
When I would try to connect to managesieve, I got an error, and mail.err contains:
dovecot: managesieve(airween@mydomain.hu): Error: user airween@madomain.hu: Couldn't drop privileges: getgrnam(vmail) failed: Permission denied (in mail_privileged_group setting)
Also I got it when I try to connect to port 4190 at localhost (with telnet), and send the generated AUTH string (with sieve-auth-command.pl). it can often help if you give versions of the dovecot and pigeonhole as well as posting the config (dovecot -n) since people may be able to spot configuration errors. sorry, you're right, I forgot it :(

Checking further, the managesieve-login process is chrooted by default. yes, I read it - but is there any way (and meaning) to configure it for not-chroot?
I wonder if it can then read /etc/group. Are you using mail_privileged_group because of the permissions on your mail storage directories would not otherwise allow them to be accessed? yes... I guess :)
If not you could try to just set mail_privileged_group to blank and restart dovecot. I leave it blank, restarted Dovecot, and now it works as well.
Thanks again for your help.
a.
So in your case, if everything including imap logins and operations are working fine without mail_privileged_group then I guess you don't really need it there. If you had needed it, I'm not 100% sure how the issue could have been resolved. You could have tried not to chroot by puttinig
chroot =
in the service managesieve-login section of your config, but even if it worked it's not a great solution.
I checked on dovecot 2.2.36 I don't have any issue with a non blank mail_privileged_group when logging into managesieve.
