[Dovecot] Dsync didn't updates automatically

[Breno Moreira]

Hi Timo,
Thanks for your answer.

Good to know that it can sync when a new mail arrives.

I've already seen this wiki page, my configuration is almost the same that
the one described there.
It syncs at startup, but doesn't syncs when a new email arrives, and that
is my problem.

In error log, some messages are printed when Dovecot starts:

Jan  4 13:22:21 srv1 dovecot: master: Dovecot v2.1.7 starting up (core
dumps disabled)
Jan  4 13:22:21 srv1 dovecot: auth-worker(4322): mysql(
supra-lb.testesupra.com.br): Connected to database Supramail
Jan  4 13:22:21 srv1 dovecot: doveadm(nobody): Fatal: setgid(65534(nogroup)
from userdb lookup) failed with euid=5000(vmail), gid=5000(vmail),
egid=5000(vmail): Operation not permitted (This binary should probably be
called with process group set to 65534(nogroup) instead of 5000(vmail))
Jan  4 13:22:21 srv1 dovecot: doveadm(mav): Fatal: setgid(1000(mav) from
userdb lookup) failed with euid=5000(vmail), gid=5000(vmail),
egid=5000(vmail): Operation not permitted (This binary should probably be
called with process group set to 1000(mav) instead of 5000(vmail))

But when there is a new mail, it only prints a success message:
