I have 3 exchange servers and have 3 sites.EU,US,CA.Each site have there own exchange server and the central site is US.the internal domain is experts.net .now my Us domain also use experts.net as its public name.
the EU and CA exchange server cannot send emails to US , since they think the domain experts.net is internal.How can i fix this problem.
Remember all 3 servers are in diferent administrative groups and we have VPN from US<--->EU & US <---> CA.(US is the HQ)
I also tried to add a connector which will forward all the emails to experts.net to the public IP of US but the emails stayed in queue.
Apart from the above what is the best way to configure these exchange servers,Is the above topology correct
