Hi, I have 2 domino server, DomA and DomB. Both are configured with Domino Clustering. By default, all incoming and outgoing email go to DomA and pass through the SMTP gateway. All incoming and outgoing mail will go to DomB if the DomA server down and the network at DomA site down. I have create Foreign SMTP Domain and SMTP connection document at DomA.

I had enable the SMTP Listener, Mail Routing and SMTP used when sending messages outside of the local internet domain at both server, Dom A and DomB. There are SMTP gateway at both side, Dom A and DomB.

Question:

  1. Do i need to create the Foreign SMTP Domain and SMTP connection at DomB? What SMTP MTA relay host should be enter?

  2. What SMTP MTA relay host should i need to enter at DomA?
