Sandy,

Thanks for your response and explanation.

There are actually no "users" on this particular server apart from "Admin".
The reason being that some of our clients have their own in-house servers
and I have added their domains to the "Accept.lst" file. It works fine but
as I say I need to keep the other buggers out.

Why a separate server? Because I was not able to find a way to get the
clients' servers to send user authentication. If you do then please let me
know as this would resolve it all for me. The users who dial-in on the
"other" server have to verify before sending mail using SMTP VRFY. That
works fine.

You  can't,  because IMail replaces the address literal (the bracketed
IP  address) with the name of the virtual host bound to the IP address
before  the  rules  engine  sees  the  message,  and adds the original
X-RCPT-TO:  after the rules have been processed--so at no point is the
original recipient filterable.
