dovecot - Mar 2014 - Error configuring dovecot instance as proxy

Hi All

I follwed the steps in the below url to configure a dovecot proxy instance.
http://wiki2.dovecot.org/PasswordDatabase/ExtraFields/Proxy

I created a new file '95-test.conf' in /etc/dovecot/conf.d/ location.
and
put the below lines in that file.
proxy=yes
host=****
port=143
nopassword=yes


However I am getting the following when starting the serice. I tried
'proxy' and 'proxy_maybe' entries, and they both failed.
doveconf: Fatal: Error in configuration file
/etc/dovecot/conf.d/10-auth.conf line 11: Unknown setting: proxy

Could anyone help me how i can resolve this?


Thanks
Bala
