Simple Exchange 2003 SMTP Questions with Front-End/Back-end configuration
Posted on 2007-11-23
I had 3 simple questions to ask regarding smtp on Exchange 2003 with Front-end/back-end setup.
I have 1x Exchange 2003 Front-end server and 2x backend server.
External MX record points to Front-End Server and Internal MX record points to the same Front-End Server. There is only 1 of each.
Question 1: when incoming email is received by the Front-end server, it automatically knows which server to route the email to based on Active Directory and Exchange Organization info, correct? If not, what else is in play?
Question 2: Lets say user Tom which is located on Back-end Server BE1, when sending an outgoing email, does BE1 server automatically sends out the email via its own smtp service or does that outgoing email gets directed to the Front-end server to send out because the internal MX record is pointing to it?
Question 3: Is there a need for me to add additional internal MX records for the back-end servers?
