[Dovecot] Dovecot 2.2. proxy_maybe and twice SSL connections

Hello.

1. I have two identically hosts

2. I have set up replication between two hosts

3. I have

   'Y' AS proxy_maybe

   in password_query.

4. password_query returns one of this one hosts

5. I set this parameters in dovecot config:

   disable_plaintext_auth = yes ssl = yes auth_mechanisms = plain login

   for enforce use encrypted connections by client programs.

When the client connects to host imap2 directly, connection is encrypted, it is good.

| client | ---- (1) ----> |imap2 (proxy_maybe='y', host = imap2)|

And when the client connects to another host, I have (1) and (2) connections are encrypted

| client | ---- (1) ----> |imap1 (proxy_maybe='y', host = imap2)| ---- (2) ----> |imap2|

but need only (1).

How do I have desired behavior? Is it possible?
