Dovecot 2.3.7 - char "-" missing

[Domenico Pastore]

Hello,

i have update dovecot from version 2.2.15 to 2.3.7.2.
I have a problem with mine java software because there is a different 
response when open connection to doveadm.

I need open socket to doveadm for get imap quota of a mailbox.

With version 2.2.15:
# telnet 192.160.10.4 924
Trying 192.160.10.4...
Connected to 192.160.10.4.
Escape character is '^]'.
-


With version 2.3.7.2:
# telnet 192.160.10.3 924
Trying 192.160.10.3...
Connected to 192.160.10.3.
Escape character is '^]'.


The difference is "-" character. The version 2.3.7 not respond with "-" 
character after opening the connection.

Is it possible to add the character again with a parameter?

Why did doveadm's answer change?
