My Dsync isn't replicating 'EXPUNGE' IMAP command

[listas at adminlinux.com.br]

I made a change in 'mail_plugins' directive, enabling 'notify' and 
'replication' globally in dovecot.conf.

Now, in my tests, the second server sees the replication of the EXPUNGE 
command only after running a SELECT command (or an click in the folder 
on MUA).

Is this the expected behavior?

* I tested with IMAP talk (telnet) and Thunderbird.

Thanks!
