Hi,

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).


Could anybody helps me to explain this message?


Thanks,


a.
