Just merged with another company and have a vpn connection between both networks and are replicating DNS. No trusts setup yet. I need to quickly configure a way for us to send email directly from our exchange 2007 server to their exchange 2007 server instead of going out through the internet. I was thinking TLS would be the best option but working with certs scares me. Is there a good article on setting up TLS. Can we just setup regular send connectors between the two servers? Thanks!
