>From the esmtpd file...

# Set AUTH_REQUIRED to 1 in order to force the client to use ESMTP
# authentication.  You can override AUTH_REQUIRED on a per-IP address basis
# using smtpaccess.  See makesmtpaccess(8).

For making local clients have to authenticate, sentences
2 and 3 are pertinent. e.g.

192.168 allow,RELAYCLIENT,AUTH_REQUIRED=1

All this does is have couriertcpd create environment
variables that get passed into esptmd and submit for
processing. See makesmtpaccess(8) for variables
understood by the esmtpd server, and submit(8) for
more variables understood once the message has been
received and is about to be queued.

If you don't have a complete list of client IP's then
it is not possible for courier to distiguish between
clients connecting and external mail servers, viruses
and hackers connecting.

P.S. Sometimes Sam's manner is abrupt to say the least,
but try answering the same question for the 30th time in
the past year despite it being hidden in the documentation.
It does get to you, I've been there and done that. In
particular the best programmers seem to get the worst case
of abruptness ('cause answering these silly questions is
eating into coding time :-). So if you do get a verbal
slap it is not you but an accumulation of prior emails,
best to take it in stride and move on.

Cheers.
