I am running GWIA GW8HP1 on Linux. I have a question about GWIA relay vs receiving email for the domain name that the GroupWise system is hosting.

My client has GroupWise system setup to as domain name abc.com. Even if I "disable SMTP relay" on GWIA, as long as I have the proper routing port 25 traffic from my firewall to the GWIA8 server, the GWIA will still process the Internet incoming mail for abc.com domain name and this is not SMTP relay traffic, right?

Is it true that the SMTP relay is only needed to enabled if I have internal SLES servers that needs to send email? I guess I can "disable SMTP relay" but add the IP addresses of these SLES servers in the exception list, right?

Hope someone can clarify the setting.
