We have set up our domino environment with relay hosts:
Domino Mail server --NRPC--> Domio Gateway Server --SMTP--> IronPort
First, you need to tell the Domino Infrastructure to route Internet Mails to the Domino Gatewa server(s). This is done via a Global Domain document and connection document (this is a std. setup).
For the Domino gateway server(s) create configuration document(s) with the following settings:
Router/Smtp->Basics:
Relay host for messages leaving the local internet domain: [ip1,ip2]
Use authentication when sending messages to the relay host: Disabled
Local Internet domain smart host:
Smart host is used for all local internet domain recipients: Disabled
For the relay host setting:
You can specify one ip or fully qualified servername here (guess without brackets)
If you want multiple servers (e.g. because you have multiple IronPorts) you should use IP addresses in [] seperated by "," like [192.168.0.10,192.168.0.11].
Domino will try ip1 first. If ip1 is not available it will fall back to ip2.
You can have more than 2 ips listed but no mix of ip and fqn.
Note: I encountered problems when using fqns.
