I need know how to detect where the emails come from.
IE: Internal emails vs external emails
Is there a field that I could check on the emails that would tell me if it came via the internet?
Would it be SMTPOriginator?
Subject: Email Address or Server?
Why not look at the received fields. That will tell you the smtp server, as opposed to an email address.

Subject: Depends
It really depends on how internal routing is done. If your Domino servers send between eachother then it’s still an “internet looking” message.
Is this the case in your environment?
Subject: No external routing is done between our servers
We have two Domino clustered servers that send/receives emails to/from an ISP.
No external routing is done between our Domino servers.
