We have about 20 domains that flow through the service. In the SMTP section, we have 2 entries (one by host name, one by IP) but they resolve to the same location. We are getting the Zix gateway and I need to add subdomains and subsequently route traffic from those subdomains to a different IP. The reason for that is so all the email doesn't flow through the Zix gateway. Only the proper messages should. So, I guess the questions are: How/where do I setup subdomains? Same location as the regular domains? How can I then route the traffic from those subdomains to a different IP address?
I realize there are other email encryption services but Zix is the one we chose to go with.
Thanks for any help you can provide.
