GOT IT TO WORK! - Not Receiving Internet Emails
Im unable to receive internet mail on our new exchange 2003 server that I wish to deploy. I can send outbound emails no problems. I send test emails to my yahoo.com account. I receive the email immediately into my yahoo account. Then I try to send a reply back, I receive nothing back on the new exchange server. I ran the Troubleshooting Assistance. Im only getting the following errors:SMTP instance fully-qualified domain name does not match DNS resolved server nameSMTP instance fully-qualified domain name does not match server name The exact full error message:msExchSmtpFullyQualifiedDomainName =webite.com The fully-qualified domain name (FQDN) of SMTP instance Default SMTP Virtual Server on GBSERVER5 is webite.com The fully-qualified domain name SMTP virtual server instance Default SMTP Virtual Server on GBSERVER5 does not match the fully-qualified domain name of the server. This may cause mail routing problems. SMTP virtual server: webite.com. Server: GBSERVER5.greatbay.local. The fully-qualified domain name SMTP virtual server instance Default SMTP Virtual Server on GBSERVER5 does not match the DNS resolved server name. This may cause mail routing problems. SMTP virtual server: webite.com. DNS resolved server name: GBSERVER5.greatbay.local. SMTP instance fully-qualified domain name does not match server name http://www.microsoft.com/technet/prodtechnol/exchange/Analyzer/391087ca-4544-4c26-a9b3-51bc46328bf4.mspx?mfr=true The value of the msExchSmtpFullyQualifiedDomainName attribute specifies the FQDN for the SMTP virtual server and must be resolvable by the Domain Name System (DNS) networking protocol. (How do I do this?) A valid DNS HOST (A) record must exist for the value of this attribute so that messaging servers that try to resolve the FQDN of the SMTP virtual server can retrieve the correct IP address and route mail appropriately. I followed the instructions. How do I exactly enter the following email domain into our DNS server? How do I resolve this issue? Where do I enter webite.com and 209.84.253.12 in the DNS server? You can email me directly. Email Domain: webite.comIP Address: 209.84.253.12 Any help would be appreciated. Thanks

You need to create an A record on your internet facing DNS server for your mail server. Then create a MX record that points to that A record. When some tries send an e-mail to your domain it'll look for an mx record. The mx record tells the sending server what host handles your mail. The A record then tells the sending server what IP address that hostname can be found on. Now what IP address to put in the A record is down to you and whether your exchange server has a public IP or is behind a firewall that's forwarding traffic to the mail server. Hope this helps, post back if you have questions. Thanks, Mark

How do I go about doing this? I'm sorry for the lack of understanding.You said the following:You need to create an A record on your internet facing DNS server for your mail server.Where do I do this? In the DNS on the exchange server? OR in my domain. We use changeip.com. This is where I updated my MX records and domain.@webite.com smtp.webite.com Priority 10, webite.com 209.84.253.12I tried the telnet test and it workstelnet webite.com 25220 webite.com Microsoft ESMTP MAIL Service, Version: 6.0.3790.1830 ready at Wed, 15 Nov 2006 12:00:27 -0500I also tried the smtpDIAG utility and it comes up fine.What's more frustrating is I had the server working with no problems. First time setup it was working great for a month, in October. On the day of the rollout, the beginning of November. We could NOT receive internet emails. I did not do any changes. I had the IMF working and other third-party spam detectors working great!The only thing I can think of is, maybe Windows update RAN on the server. Is this possible? Because one day I came in I saw it at the login screen. I never logged out.I forgot to turn off Windows Automatic Updates.

GOT IT TO WORK! It was my SMTP access connection. Heres my Mail Flow Diagram: In the Default SMTP Virtual Server, Access tab, I changed both the Connection and Relay from Only the List Below to All Except the List Below. I had no idea it would be simple as that!

I had the same problem- could send but never get. My situation was I had a WAN IP address change in the company - new IP, gateway and DNS (no provider). We host our own email. I made all the changes on our exchange and it seemed like it worked, but it didn't. What was the issue - My MX record was still pointing to my old WAN IP address. Once I changed it to the new WAN IP - inbound email was routed correctly. It was - when I sent mail from my yahoo to my work, it was routed via DNS name - that DNS had to view the MX record. Wth the wrong IP, the mail was just dropping off and never reaching work. With the correct IP (which that IP translate into my subdomain of mail.company.com) it was then routed correctly. Just wanted to share that with anyone else reading this.

I know it has been awhile since you posted on this topic but I'm hoping you still keep an eye on it. I'm trying to set up my first Exchange server and have come to this exact problem. I host my own site and email (when it starts working!) and, looking at your solution, I'm not sure if I am to create these records inside DNS on my server or on the internet server which hosts my details (MyDomain). Since I'm sure there is a relationship, perhaps you could specify the recordsets necessary on each side? I have a single server named, you guessed it, "server." Thanks for any help you can give me!!!

The reason you need to create these records in DNS is so that other MX servers on the internet can locate your mail server. So you need to create these records on the internet server which hosts your details (MyDomain).My first reply to this thread will give you a basic flow of how this works, but these articles will give you a more thorough understanding. http://www.computerperformance.co.uk/exchange2003/exchange2003_MX_records.htm http://www.msexchange.org/tutorials/Configuring_DNS_for_Exchange_2000.html Once you've got this configured, other mx servers can locate your server. You next step is to make sure they can talk to it (ie. make sure your firewalls forward port 25 correctly and your ISP isn't blocking it either). There will also been some exchange config to be done to get this working so what version of exchange are you playing with? Hope this helps but post back if you have any other questions. Mark
