Hmm, I feel I have to re-send, to correctly attribute the former text to 
Michael Grimm (rather than to Цветков Алексей). [Corrected above.]

In any case, please provide some link with info on how to set this up 
correctly for continuous real-time dsync.

I am using ldap-hosted accounts and Maildir. Dovecot runs on CentOS 6.3.

It seems to me that the mirroring examples at: 
http://wiki2.dovecot.org/Tools/Dsync refer to a one-time operation, 
rather than to a continuous/real-time function.

Sincerely,
Nick
