To only a single Exchange server? Why would you need Dovecot proxy at  
all there? Just use whatever dummy TCP proxy.    
      Yes, to only single.  
  I am trying to configure SMTP AUTH (Postfix+Dovecot SAS with Active Directory users account) and IMAP proxying to Exchange.  
So now my problem is in IMAP proxying.  
SMTP auth separately works fine.
