MX Record and A Record setup for SBS2003 server
Posted on 2004-11-24
I have setup a SBS2003 server and I have some confusion on the MX record
and the A record that should point to the new exchange server.
Heres the details:
SBS2003 server w/ static IP address behind a firewall that port
forwards to the new server, 192.168.16.3 (single nic) The internet works
I want my third part ISP (Verio) to forward the email to the external
ip address of the new server. The nameserver and website should stay
What exactly is the procedure for this?
This is what I have done so far:
-Set a new A record at the Verio server and called it:
xyzNet.xyz.com. IN A xx.xx.xx.xx where xyz is the name of the
established domain and xx.xx.xx.xx is the ip address of the new
-Set the MX record:
xyz.com IN MX 10 xyzNet.xyz.com. with the ip address to the new
Added a 2nd MX record:
xyz.com IN MX 20 xyz.com with the ip address of the Verio server
(where it is now.)
Is this correct? Do I need to create an A record? or just the MX
Do I need to make any changes on the SBS2003 Exchange Server? Does the A record in the Verio Webserver need to correspond to anything on my exchange server?
Do I need to wait for propogation through the InterNic servers before it starts working?
any help would greatly be appreciated.
