RE: Unable to send mail between Routing Groups



Greetings all,

After deleting and re-creating the connectors, I was (at first) able to send
an internal email successfully from the server in SiteA to the server in
SiteB, but was unable to send internal email from the server in SiteB to the
server in SiteA.

So I turned on diagnostics logging on the server in SiteB and tested. The
emails which should have been categorized to go through the RGC were instead
attempting to be sent through my smart host. I scoured the configuration on
this machine until I found (On the virutal server-> Delivery-> Advanced tab)
that I had filled in the smart host field with my smart host on the serv er
in SiteB but not on the server in SiteA.

So, my bad. Hope someone else does not have to wrestle with this same problem.

Be sure to check 'everything'
