MX Record and A Record setup for SBS2003 server
Hi Folks,
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
fine.
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
at Verio:
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
server.
-Set the MX record:
xyz.com IN MX 10 xyzNet.xyz.com. with the ip address to the new
server.
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
record?
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.

Hi Dave.
The only thing I did on the SBS2003 box is to make sure you have an SMTP connector setup in Exchange 2003. It does take some time to propogate, say 72 hours max, but I did this all on a Friday night, and it was up and running on Monday morning. At first, the traffic was being blocked. Then I realized I needed to open Port 25 for SMTP traffic. Once I did that, the emails came flying in.
Good luck!

Ok, the exchange server is working now for outgoing traffic so I presume the SMTP connector is setup. What is I was confused with was actually changing the A record. I didn't know if it was possible to just change the MX record or if it needed a corresponding A record changed as well.
Thanks again.
Dave
Thanks again.

You usually need an A record to point to the MX record. Looks like you've got everything covered.
Thanks for the answer/grade - enjoy the holiday weekend.

I will, you do the same

Thanks for confirming. That is essentially what I did. Did you have to make any changes on your SBS2003 server? Or is the default setup sufficient? Did it start working immediately? or did you have to wait for it to propogate?
thanks,
Dave
