I have 2 Domino Servers as follows:
Connection document is setup between both servers. Port 1352 is open in both directions and replication occurs regularly.
As both servers are on the same Notes Named Network (NNN), my understanding was Notes would route mail natively from ServerB to ServerA as it knows ServerA is the mail sender.
The failure message on ServerB is:
'No route found to domain external-domain.com from server ServerB. Check Server, Connection and Domain documents in the Domino Directory.'
Any suggestions for what I am doing wrong?
