I have been asked to relay messages from a sendmail server in the DMZ through our Domino hubs. In case this sendmail server was hacked, I have also been asked to only accept mail when it is coming from a particular sender and only relay messages if the recipients are part of a controlled list. I don’t see where I can set these type of controls they are asking for. Any thoughts?
Subject: Configuration document
The allow from recipients should be:
Router/SMTP - Restrictions… - Inbound - Inbound sender controls - Allow …
and you can add the IP here:
Allow messages only from the following internet hosts to be sent to external internet domains: (Same Inbound tab)
I am not sure if you can make a particular user only relay to some domains without restricting it to all the users.

I was looking at the configuration document but I need to be able to control what recipients this sendmail host can send to (without knowing the sender’s address). I don’t see where I can just apply rules to this one host without impacted my other messages from other hosts.

How many senders? I could think that you could create several server rules, to delete the message but that would be really difficult.
Most simple it’s to install a new server (Or a single one with two partitions) but I know it sounds a lot.
Another thing you could do it’s to make the server send always to a mail account, and then create an agent there to forward the email if the sender is inside a group in your NAB. That’s better but you need some coding.
Google: “Good forwarding agent” for the code of the forward. Then you could add the Group checking somehow.
