Cannot recieve external e-mails HELP!
|
|
|
| I have setup a little test network. My problem is I cannot recieve external e-mail from anyone. I can send e-mail out to anyone on the internet, I can send and recieve e-mails on my internal network and I can also use OWA. My network consists of 2 pc's with 2000 advanced server with 2000 exchange server installed. Any help will be gratefully appreciated. My only thinking is I wonder if I have to register my test domain name to recieve external e-mail from anyone. Once again, thanks for the help in advanced.

| Dear DJ,
My experience (limited) is with Exchange Server 5.5, but I'll offer two suggestions. Please note I am not running Exchange Server 2000, so you'll have to adapt my advice to its corresponding spot in Exch2K.
If you can send outbound e-mail, your DNS is probably OK. On the incoming side, you must enable routing. On 5.5 here's the drill-down:
Start Exchange Administrator
Go to site -->configuration -->connections
Highlight Internet Mail Service
Go to the routing tab
Click on the radio button "reroute incoming SMTP Mail(required for POP3/IMAP4)"
Add your SMTP provider's domain (for example concentric.net) and have to route to <inbound>
Close out the dialog boxes
Restart the Internet Mail Service
Hope this helps. | |

| Thanks for the response, There is no exchange administrator in 2000. I'm not to sure on how to check this in 2000. If anyone can help I would sure appreciated it. I still can't recieve e-mails from anyone outside of my network. Thanks in advanced DJ  | |

| Look for the Exchange System Manager. | |

| If you "test domain" isn't a registered domain on the internet, then there is no way for external users to send you mail.
You need to register a domain, and on your DNS servers you will need an MX record to identify your mail server. All external clients that try to send you mail, will first contact the DNS server that is authoritative for your namespace, for the MX record. An SMTP server will then forward the mail to the MX server for your domain, and however you have your internal mail routing set up will determine how mail is finally received by the addressed recepient. | |

| I thought that what the problem could of been, not having registered my test domain. I just wanted to be sure and have someone confirm my theory as to why I couldn't recieve external e-mails. I'm a newbie at exchange and just trying to learn it with hands on with my test lab I have setup. I have two pc's with advanced server and exchange 2000 on both. Everything was going fine until I couldn't recieve external e-mails. I also couldn't get my 2nd server to become a member server in the beginning because my DNS wasn't set up correctly on the PDC. Hands on makes all the difference to find out why things don't go according to plan. Thanks for all of your feedback. This sure puts my mind at ease.
Added note: I was going for my CCNA but I felt I needed to know exchange first before I go on to the Cisco cert.

| Hello again, DJ.
Lucidity's advice is right on the money if you want to host your own e-mail server for "dj-domain.com" (or whatever your registered domain will turn out to be).
Another option: domain-registration services will offer other features such as hosting your Web server, e-mail addressing with your domain name, etc.
In my case, I have registered a domain name, but retained the e-mail service that came with my DSL service. My drill-down post is how I set up Exchange Server to send and receive SMTP/POP3 mail in that scenario.
Finally, for Active Directory to work, your internal DNS setup has to be functional (and you're grasping that point). When you can successfully ping your domain controller by its fully qualified domain name, your success rate in machines joining domains and having group policy work improves dramatically.
Hope this helps. | |

| The help you guys provided has help me a lot. I have been doing all of the exercises in this exchange 2000 book I have. Now I'm learning about groups and creating users in exchange. Hopefully, I'll be ready for the test in a couple of weeks at the most. Any good testing software suggestions? Thanks for all of the help.
