Can't find mailsever when joining domain

Here is the scenario.

Client with several WinXP Pro machines running in Workgroup configuration. I
added a Win2000 Server and set up a domain. Installed a Netgear FVS318
firewall/router. Set up the server as DHCP and DNS
server.

I then joined each machine to the domain. All went well, however, now none
of the clients can get their emails. They keep getting the error message
that they cannot find the mail server.

I checked the DNS settings, added a "Mail Exchange" host, checked the DHCP
to make sure it is giving the correct DNS addresses but I cannot find why it
is not finding the server.

One piece of (perhaps) significant information: the domain is called
"mydomain.com". The email pop and smtp is looking for "popd.mydomain.com"
and "smtp.mydomain.com".

Any ideas what could be causing this? Do I need to let specific email
traffic through the firewall?


thanks

Where is the mail server?
If the mail server is hosted by ISP in your internal mydomain.con forward
lookup zone create a host named popd and smtp pointing them to their
respective IP addresses.
If the mail server is hosted by ISP point them to the public address. If it
is hosted locally point them to the private address.

Alternately, you can create the names as delegations then give them the
address and hostname of the Authoritative DNS servers on the internet.

Kevin,

Thank you for your reply. Please forgive my ignrance, but I need a bit more
step-by-step help.

The ISP hosting my domain is external to our company. So I am not quite sure
how to read your response. Can you give me an example of what to do?

thanks

Hi Nate,
Internal Domain name same as external domain name?
Two methods for fixing this,
1 In the internal DNS forward lookup zone for your domain name, create a new
host record named mail, www, or whatever, then give the host record the IP
address of the public mail server or site. This will work fine so long as
the provider IP does not change, in that case use recommendation 2.

2 In you internal DNS forward lookup zone for your domain, create a new
delegation for the mail server or website name, i.e. mail, pop, smtp, or
www; then point the delegation to the authoritative DNS servers for the
public domain.
You must use the exact name as hosted on the public authoritative DNS and
the delegation must point to the authoritative DNS server for this to work.
This is the most reliable fix for this because some providers irregularly
change the addresses of their sites and servers without notice.
