Setup DNS on SBS 2003

I am trying to setup my server to be able to send and recieve e-mail for two domains.  I can currently recieve mail externally but I can not send mail externally.  Internally everything works fine.  I believe I have narrowed the problem down to a problem with DNS.

The two domains that I am going to host are www.mcbreartyfamily.com and www.dmkmarketing.net.  I have a dynamic ip address and am using DNSexit to resolve the IP address for my domains.  

I have never setup DNS before.  Can someone please walk me through it step by step.

Any help that you can provide would be greatly appreciated.

Thank you,
Kevin

I think we need a little more info..  for instance, are you running your own Exchange Server on this network?  Does it involve a Domain Controller (if so, you already should have DNS setup)?  Or are you just popping an external mail server, and sending using an external smtp server?  Or, are you just using IIS and its mail services?

There are lots and lots of articles written on DNS, but for a start, here is one of the easiest to understand when setting up DNS for the first time on a Windows box:

Hi kmcbrearty,

Since this is an SBS, it is Exchange, and it's not really about DNS, but rather just following the Configure Email and Internet Connection Wizard (CEICW) correctly and then adding another domain to the server for email.  Then, just making sure that your MX records at DNSExit are correct.

So, first run the CEICW according to this:  http://snipurl.com/ceicw

Then, to add the second domain please read this article:  http://snipurl.com/sbs2domain (which will also include info about routing the second domain to an alternate web page if that's going to be on your server as well.

Finally, go to your admin panel at DNSExit and make sure that the MX record in the DNS Zone file for each domain has your server's FQDN (fully qualified domain name -- ie, sbs.dmkmarketing.net -- 'sbs' being whatever you call your server)  If your zone file already has a wildcard "A" record (ie, *.dmkmarketing.net) then you're done.  Otherwise, you'll need a CNAME record which points sbs.dmkmarketing.net to www.dmkmarketing.net.

That should do it for you!

Good Luck!

Thanks for the help.  I had entered the FQDN on DNSExit incorrectly.  I didn't fully understand what they were asking for, but your explanation made a lot of sense.  E-Mail is running just fine.  

I appologize for the delay in getting back.  With the holidays I was kind of busy, and through this whole process I hosed my SBS installation and had to reinstall.

Again thank you for the help.
