[Dovecot] "Dumb" proxying?

[Ruben Lang]

Hi Dan,

you can set up a static/simple passdb. All you have to do is to return 
some
extrafields for proxying.

We had a 'passdb checkpassword' and I simply set those environment 
variables
in our checkpassword script (python).

    os.environ['proxy'] = 'Y' # if there is a proxy field, proxying is 
enabled whatever the value is
    os.environ['host'] = '192.168.0.1' # the server to proxy the 
connection to
    os.environ['EXTRA'] = 'proxy host' # passdb checkpassword needs to 
know about the extra fields
    os.environ['USER'] = user # the user to use
    os.environ['HOME'] = '' # set on the 'host'

As you can see, you only have to enable proxying and set a destination 
host
and all connections get forwarded 'dumb' ;).

Greets,
Ruben Lang
