Apparently it either doesn't work - or I'm not doing it right.

To be a little clearer:
- I have a Internet relayhost running Postfix.  This is where the 
TLS/SASL is needed.
- On an internal server, I have a Postfix server for internal mail 
delivery with Dovecot for IMAP access.

As I type this - I guess I do have two list of valid e-mail users - one 
in the relayhost's passwd file, and one in the internal host's passwd 
file.  Well - not entirely - the aliases are placed on the relayhost's 
alias file.

So the actual "accounts" are listed in the internal host's passwd file - 
which the relayhost should NOT be able to access!  rimap seemed like a 
simple plug-n-pray solution - and I'd still like to know (just 'cuz!) if 
it will work.
