Re: Basic setup of client e-mail on an externally-hosted domain/se

Check the routing table on the server. A more likely cause is that there is
an improperly configured static route to the mail server's IP or network.

Doug:

I had a friend ping the mail server from his own personal network and it
is
set to not reply to pings. He suggested that my problem lies with the
firewall in Windows 2003 server since this feature was not contained in
Windows 2000 server. Is it possible that the firewall is
default-configured
to allow ports 80 and 8080 for web but that 25 and 110 are locked down and
need to be opened? If so, how would I check?

I confess that I do not understand the configuration of this network,
but:
If the mail server name does not resolve to an IP or resolves to the
wrong
IP, you may be able to solve this with a hosts file on the clients. If
the
name is properly resolved, run tracert on the IP and see where these
packets
are going.

Can't ping either one.

Well, you need to eliminate the possibility of routing or name
resolution
issues first. Can clients ping the IP of the Verizon mail server?
Can
they
ping the name?

I have been running servers with Windows 2000 Server for several
years.
Recently, we set up a brand-new LAN in one of our buildings and
the
new
server has Windows 2003 Server on it. Our e-mail is hosted by a
provider
(Verizon) and clients that are using a private IP address range
connect
fine
through my firewall/router device on my LANs that have a server
running
Windows 2000 Server. Two separate domains are in this category
and
one of
them connects to through the firewall/router device in the other
building
using a trust. When I set up my new server (that runs Windows
2003
Server),
I duplicated all of my internal routes, etc. thinking that this
new
domain
would get through to the firewall router in another building just
like
the
other "slave" domain does (we are a Town and we are connected over
the
cable
network).

Clients on the new domain and new LAN can access the Internet just
fine
but
cannot send or receive mail. Also, interestingly, if I configure
a
client's
NIC to bypass the server and to access the cable modem directly,
it
can
access the web AND mail works fine.

As such, it seems that something that I am not familiar with in
Windows
2003
Server needs to be configured in order that the mail requests can
come
and
go
freely between the LAN NIC on the server and the cable link NIC on
the
server. Again, this is not a general connectivity issue since the
web
connection works.

What gadget in Windows 2003 Server that controls the simple pass
through
of
e-mail to and from clients do I need to find and how do I need to
configure
it. This must be a new element that was not found in Windows 2000
Server.

Thanks for the help.
