We've started to work with a new client. Unfortunately we have inherited a rather bad network setup.
There are two sites - each with an SBS 2003 server. Email is hosted with an external company and retrieved by each SBS via pop connectors. For the second site a sub domain has been created so this email system works as it should.
The client is planning to change the network setup at the end of the year but we are currently doing some work to try and get to that stage.
The client wants to remove the third party email hosting company altogether.
I thought this seemed possible - can't we just point the MX records of the domain and sub domain towards each single office?
How would that work?
If someone sends an email to firstname.lastname@example.org then the MX record will tell it to go to the main site.
If someone sends an email to email@example.com but the user is actually at firstname.lastname@example.org how will the DNS know to send to the second site?
