Can we set following rules on the Domino Server for Inbound SMTP relay:
1. Allow mail from external SMTP servers ONLY if it is destined for XYZ.COM
2. Allow ALL (xyz.com as well as non xyz.com) mail from ONLY one specific SMTP Server e.g 188.8.131.52
This is to ensure that only 1 SMTP server can relay using my server, for every other server, I will accept mail only for my domain.
Thanks in anticipation for your help.
