I've got an exchange mail server on my main server. 10.x.x.179. I've got an external web site, dougnc.com at 64.x.x.131. This is translated by my firewall to 10.x.x.131. 10.x.x.131 is one of 4 ip's my web server listens too.

Now how do I set up the mx record on my dns server to go from dougnc.com to pell.alliance? I've tried everything. They're seperate domains, so the dns looks something like this:

Forward lookup
aliance active dir.
dougnc.com standard

> set q=mx
> dougnc.com

dougnc.com MX preference = 10, mail exchanger = dougnc.com
dougnc.com internet address = 64.132.200.131

Mail goes out fine, doesn't come in. I've got the right stuff enabled on the firewall, and before I reloaded my server I was getting mail in.

Any help would be greatly appreciated.

Do you have the Generation Rules set in System Manager? Both domains need to be active.
 
Thanks! I added another smtp address, with @dougnc.com.

I can now send e-mail to doug@dougnc.com on my internal network. Still not working from outside, tho.

Should nslookup q=mx dougnc.com resolve to the internal 10.x.x.x address, or the external dougnc.com address.

Thanks!

Your Public dns needs to have an mx record for your mail server if you want people to send you mail externally. currently I can't resolve the mx record from your public dns.

Do you have an MX entry on that DNS server?

Sorry. I had moved the mx entry from dougnc.com to alliance.

Here, I put it back. Is this right, or should the mail exchanger point to the inner ip address?


> set q=mx
> dougnc.com
Server: UnKnown
Address: 10.x.x.179

dougnc.com MX preference = 10, mail exchanger = dougnc.com
dougnc.com internet address = 64.132.200.131

You could point the MX record at your firewall/router and have it route all traffic on port 110 to your mail server. Marc Creviere
 
Thanks. I only had port 53 open. But it still doesn't work.

Now I'm obsessing : - ).

Doug
 
Thank you everyone! It works. Now I can get back to some real work : - ).

It was the Recipient policy. I would never have figured that out on my own. The final problem was I had somehow unchecked the Only mail-server for this domain box. And it's nice to know I just have to point the mx pointer to my pix, and not worry about internal setup.

Do I need pop, port 110, access? I have the smtp port open, who uses pop?

Thanks!
