GWIA - "Will Not Relay" Message

Question

I have a GroupWise mail system set up with two mail servers:
1 Windows Server 2003 SP1 - GFI MailEssentials, GFI MailSecurity, and
GroupWise WebAccess front-end.
1 Netware 6.5SP6 - GroupWise 7.1 GWIA, POA, MTA, and WebAcc / Document Agents.
The way our system works is that mail is delivered to our ISP, and picked
up by the GFI MailEssentials server. GFI MailSecurity scans the mail, and
if all is good, forwards it to our GroupWise server. Our server is
configured to only accept relaying through the IP address of the other mail
server.
Recently I was at the console and noticed that on the GWIA screen, there
was the following:
00:36:53 454 DMN: MSG 1854 Will not relay: [email protected] (219.91.104.28)
Does this mean that a message from [email protected] was not able to be
delivered to one of my users, or does it mean that someone from the outside
is trying to relay that message through my server?
This is the first time I have seen this message. I browsed the logs and it
only showed up once.
Thanks,
Eric

Answer 1

How would someone from the outside know I have a mail server? I have my
firewall configured to block tcp and udp port scans. I ran a test and it
showed to be "invisible" to the outside.
Is there anything I should do?
