Documentation for Novell Groupwise 6.5 maybe found
For GWIA go to the GWIA properties in NWADMIN, select the Access Control tab and
then SMTP Relay. In the SMTP Relay dialog choose Prevent message relaying. Restart
GWIA. For the SMTP/MIME Gateway (dated 8/15/96 or later); edit the GWSMTP.CFG
file and add the /norouting switch, then restart the gateway. Make sure GWIA has
been patched to the latest version available. NOTE: GWIA will accept the relay
message, place it in the GWPROB directory and send an undeliverable back stating
ACCESS DENIED to the sender. GroupWise 6 does not do this as it does not accept the message.
