Possible IMAP IDLE bug in Dovecot 2.2.18 and 2.2.25

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.
  
 Bellow the LOG FILE:

Possible IMAP IDLE bug in Dovecot 2.2.18 and 2.2.25

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.
  
 Bellow the LOG FILE:

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

After login Dovecot proxy no longer understands anything about the traffic. It
simply keeps proxying the IMAP traffic between the client and server. So Dovecot
isn't the one generating the IDLE commands, it's Outlook.

That is stranger then. Maybe it has something to do with having a different
CAPABILITY response. You could try setting imap_capability setting to same as
what Smartermail announces. Other than that I can't really think of anything
specific that you could do or we could fix on Dovecot code.
