[Dovecot] Trying to get Dovecot Director Proxying working

[Murray Trainer]

Hi All,

Firstly, thanks for all the really helpful responses to my previous 
questions "Architecture for large Dovecot cluster" and "Sizing MTA 
servers".

I am now trying to get a Dovecot director proxy working with a single 
backend mail server.  When I try to connect to the dovecot proxy on the 
pop3 and imap ports I get connection refused.   I want the 
authentication to be on the backend mail server initially.  I am not 
sure if I am  missing something?  More info below...

Thanks

Murray
