Hi,

Yes, the image is spot on. The Secondary only ever gets email when the primary is down due to MX records.

But if the Secondary is in firewall mode how is Xeams going to accept the message in the first place if the Primary server is down since it only proxies the connection?

I was under the impression that in firewall mode the secondary server (exchange) MUST be up? Hence if the Primary Xeams server is down how will the Secondary Xeams server connect to it to proxy the connection?

Many thanks.
