Hello Guys,
  I guess that I found a bug in Dovecot 2.2.18 and 2.2.25 versions. The
problem it's when I try to connect in a Dovecot used a proxy to another
e-mail server (in our case it's a Smartermail Server) the DoveCot send a
lot of IDLE commands to the destination server. With that, the LOG files
grow and grow and grow :(
I make a test with 1 connection only and if you see the log file in the same second the dovecot send 25, 40 IDLE commands. But, when I disconnect the client (outlook 2013) the dovecot continue to send the IDLE command for
some seconds.
     If I try to connect directly to Smartermail with Outlook this don't
occurrs.


Just to be sure, the behaviour you are expecting is that IDLE is not used, right?

Also, looking at the code, IDLE is only used if your server claims to understand it, so could you do following:

telnet backend-host backend-port
a CAPABILITY
a LOGIN username password
a CAPABILITY
a LOGOUT

and provide the output.
