1.  Add VERIFYCLIENT EXIT ENDVERIFYCLIENT to SMTP CONFIG
2.  Copy SMTPVERX (SAMP?)EXEC to 198 and change it to display the IP 
address of the client.
3.  Have it set the return code to 0

Normally you would specify "YES" instead of "EXIT" in order to get the 
SMTP server to validate that the host name on the HELO/EHLO matches the IP 
address of the client.  The exit gives you exquisite control over that 
process.
