I'm trying to set up an X.400 connector between two Exch. 5.5 sp1 sites. The servers are on different domains and tcp/ip networks. They are connected by an ethernet LAN. The domains have a two way trust. The remote MTA is the name of the remote server and the local MTA is the name of the local server. Server A is rejecting the requests of server B to make a connection. Any ideas what might be wrong?
