I have been tasked with creating send and receive connectors for two different forests that do not currently have a trust. This is for an exchange 2010 organization (both of them. I have googled many sites and while they provide good information on creating the connectors and recievers ex: http://exclusivelyexchange.com/configuring-smtp-connectors-in-exchange-2010/
This is an excellent article and I use internet then specify the domain and then I would like to use DNS MX records.
The big issue is in which I am confused about is this.You have a company for example called contoso and another company called Microsoft. My question is how do you point and create a MX record to see Microsoft while you are in contoso forest and how do you create a contoso mx record while in microsoft forests. As far as I know this is a 3 three step process
1) create send connector
2) create receive connector
3) configure MX records
