Configuring MS Exchange Server 2000 to accept Incoming Internet E-Mail
|

| Hello!
I have been trying to configure an Exchange 2000 Server to accept
Incoming Internet E-Mail, but to no avail! Of course I am a novice and
am new to Exchange.
This is what I have done so far and what is functioning so far:-
Configuration:
1) A Web Server (Windows 2000 Advanced Server with Active Directory)
with a Static IP and a dedicated cable to the Internet Backbone. The
machine is our own and is physically situated at our Local ISP's
premises.
2) MS Exchange 2000 Server with one Virtual SMTP Server and One POP3
Server bound to the machine's Static IP
3) All IP address have been permitted to access the server.
4) An MX Entry in the DNS Server, pointing to "mydomain.com"; which
server is the Primary DNS Server of our domain, configured with the
Domain Registrar. Note that this DNS Server is not our ISP's.
5) Four Users created in Active Directory, all with e-mail addresses
such as User1@mydomain.com, User2@mydomain.com, etc. They are
reflected correctly in Exchange's System Manager.
6) Two e-mail facilities with external service providers
(K1A2U3@Yahoo.com, me@myisp.com)
7) Outlook Express with two accounts, one configured for
User1@mydomain.com and another for User2@mydomain.com with both the
Incoming and Outgoing Servers pointing to our machine's static IP.
8) Testing is done through an external machine at our office with an
ADSL 64KBPS modem.
Functioning modules for the two User accounts configured in Outlook
Express:
1) User1@mydomain.com can send e-mails (using the configured Oulook
Express account) to
.............user2@mydomain.com
.............user3@mydomain.com
.............user4@mydomain.com
.............K1A2U3@Yahoo.com
.............me@myisp.com
2) So can User2@mydomain.com
3) User1@mydomain.com and User2@mydomain.com can recieve e-mails sent
by the other.
Functioning modules for the two external e-mail accounts:
1) Both K1A2U3@Yahoo.com and me@myisp.com recive mail sent by
User1@mydomain.com and User2@mydomain.com
2) Both K1A2U3@Yahoo.com and me@myisp.com can send mail to
User1@mydomain.com and User2@mydomain.com; i.e., No error message is
recieved such as "Unable to resolve domain name" or "Relay Denied",
etc. Nothing comes back!
Non- Functioning modules for the two User accounts configured in
Outlook Express:
1) E-Mails sent by K1A2U3@Yahoo.com or me@myisp.com do not get
recieved.
Question:
How can we get e-mails sent by general Internet Users into our
Exchange Server's User Mailboxes and download the same to a client
such as Outlook Express?
Thank you for your patience and effort in replying to this query.
Regards

| I think you're making things more complicated than they need to be. Forget
the POP mailbox issue - just concentrate on your server receiving mail...
1. Your internal DNS server is not where your MX record goes, unless you're
running your own public DNS server. Your ISP or whoever has DNS authority
for your domain should have created an A record (such as
mail.yourdomain.com) and pointed it to your public IP. Then set your primary
MX record to mail.yourdomain.com. Can your ISP telnet to mail.yourdomain.com
on port 25?
2. Is your recpient policy set to handle mail for yourdomain.com ?
3. Is port 25 open in your firewall, and if you use NAT, do you have a
one-to-one mapping of public to private IP?
See http://www.msexchange.org/pages/article.asp?id=59 for more detail.

Is the domain in question defined in a recipient policy on the
Exchange server? If not, add it.

Maybe that is the issue. Will do so and revert on the status.

That is not an issue at all for us. Should it be?
Thank you both for your assistance. Will keep you posted on the
developments.
Also, I am now trying to configure Terminal Services for Remote
Administration. That will help a lot as I don't have to keep pleading
with our ISP to gain access to the Server. Another question, loosely
related to the subject:- Is it advisable to use the in-built Win2K
Terminal Remote Administration Components or use third-party tools
such as VNC, in terms of Bandwidth Usage, Security and Effectiveness.
Thanks again for all your assistance.

Resolved!
Turns out all I had to do was to check the "anonymous access" in the
SMTP Virtual Server's Access Properties! I was asking every server on
the internet to require a UserId and Password to send mail to my
server!!!
Thanks again guys for your assistance. Much appreciate it.
PS: I am using both Terminal Server and VNC to remote-administrate.
Each has its own plus points!
