[Dovecot] dovecot-2.2.beta1: do not removes e-mail with enabled replication

[Евгений Басов]

Hello.

I'm created two installations of dovecot-2.2.beta1 with identical
config. Without replication each server works good. With replication
enabled every changes are replicated between these ones.

When I probe remove or move some email in another folder it is
disappears and reappears again and again in source folder and appears in
destination folder. Thus increasing number of letters like with copy.

Possible reasons cause of the problem:

- bug
- configuration settings of dovecot
- users with wich dovecot works and users rights.

Which version is true? If this not a bug, what should be corrected in
the configuration?
