smtpserver s18 vs. user@[x.x.x.x] reject policy

[Simon Brock <shb@widearea.co.uk>]

Unless I have had made a horrible mistake somewhere, there is a 
problem with the policy rejection in s18.

Having discovered that one of my machines -- a RedHat 5.2 machine -- 
was registered on ORBS I updated it to s18.  Unfortunately it still 
accepted the problematic address so I checked out a Solaris 2.6 
running s11 and that rejected it.

I then tried the same test on the same machine with different 
smtpservers as shown below.  The s18 version allowed through the 
offending address each time.  I have deleted and rebuilt all db files 
each time.

Am I wrong or is the smtpserver wrong?

Regards
Simon.
