Help with cyrus-imapd, cyrus-sasl, postfix and lmtp

[Dale J Chatham]

One more point.  Can't one authenticate with saslauthd running on a 
remote machine?

So, could I:

Internet    DMZ             Internal
========    =============   ==============
mail           ->  Postfix                 -> lmtp
                             ^                            |  |
                             |                     +--- +  v
                             |                      | Cyrus-imapd
                             |                      |       |
                             |                      |       v
                             +-----------------+> saslauthd
