The named set-up has changed from 4.01 to 4.1 and it is causing me some problems (I think). Can someone explain the db. files to me? There appear to be three different ones:
db.[domainname]
db.e-smith.[domainname]
db.myconpany.xxx
I'm wondering which ones control what (i.e. internal/external)?
The problem I'm having is that I'm not recieving any email from the outside world. I can send email out. I can connect via the web no problem. I can do an nslookup for the domain with no problem, but I cannot do a mx lookup for my domain externally. The nslookup -query=mx on the e-smith machine looks correct. Everything worked fine on my 4.01 machine.
Any ideas?
Thanks

Let me provide a little more information.
On my 4.01 machine I followed the instructions posted here: http://forums.contribs.org/index.php?topic=9682.msg36755#msg36755 to set-up a public dns server on my e-smith machine. I've now moved this machine (actually a test machine) forward to 4.1, and the public dns doesn't work correctly now. Or at least the email doesn't.

Ok. Getting closer. I'm now guessing that the problem has something to do with the packet filtering. Could this be the case?

That, and more. We do not support or suggest running a "full" DNS server
on a e-smith box. This is a major customisation, and is better discussed
on the devinfo mailing list.
There are major security and reliability issues with running a "full" DNS
server - please ensure that you understand these fully before modifying
the configuration.
There are a large number of competent free or inexpensive DNS hosting
services available.
