so I'm ready to change our firewall rule to route mail through 2013, example
old
public 123.123.123.123 > 10.10.10.3
New
public 123.123.123.123 > 10.10.10.4
What do I need to do, do I remove the old CAS servers from the send connector, do I have to make any changes to OAB, or any other connectors, what about my relay connect. We do not have an edge server we use a public provider for SMTP.
Just looking for some step by step if you can help, thanks!!
