  • No incoming mail!

    Hi, I really hope someone could help me out, I'm completely lost here...

    I've got an Exchange 2003 server that has been working okay for months. It's a single server acting as mail- dhcp- http- and fileserver. We've had some hardware problems due to the server not being "big" enough so I've had to swap network cards a couple of times. There's a new server on the way but still a few weeks away.

    Last monday we stopped getting incoming mail. We can mail on the inside, within the domain I mean, but no external mails come in. There were no software or hardware changes made by me or anyone else within a week before this happened. I suspected another hardware failure and tried swapping the network card again but that wasn't it. Still no incoming mail.

    Outgoing mail works just fine. And I can telnet to the server on port 25, and it replies. I can send mail that way too. I've double-checked the firewall and it lets port 25 and 443 through OK. I even checked through www.canyouseeme.org and that confirms port 25 is open.

    I found this article, and I've got the same symptoms as this guy: http://www.broadbandreports.com/forum/r18628494-Exchange-2003-not-processing-incoming-mail
    Except I tried to run ADSIEDIT.MSC but got an error back saying Windows can't find the file... somehow I don't think it's the same problem, just the same symptom.

    I cleared the logs and activated the most detailed logging an hour ago and this warning is all I got so far:

    9302: The transport configuration type 2 for the directory entry with DN or GUID CN=MICROSOFT MTA,CN=SERVER,CN=SERVERS,CN=FIRST ADMINISTRATIVE GROUP,CN=ADMINISTRATIVE GROUPS,CN=LINFORD,CN=MICROSOFT EXCHANGE,CN=SERVICES,CN=CONFIGURATION,DC=LINFORD,D C=SE is not one of the supported values. Reconfigure the transport configuration type in the identified directory entry. [BASE IL OPERATOR 23 217] (

    This warning has returned 8 times the last hour, other than that there's no errors in the app log. There are none in the system log at all yet.
    I did get some other 921/922/1023 event id's earlier this week but I haven't seen them again. It had something to do with users / system not being able to authenticate.

    Does anyone have a clue? I'd appriciate it!

    Do you get an NDR if you send mail to that domain from an external domain?

      You haven't really done enough basic diagnostics. Confirming the port is open is fine, but doesn't really tell you a great deal.
      You need to see what is happening when SMTP traffic is trying to be delivered.

      Start with this site: http://www.dnscolos.com/free-dns-report.html
      Enter your domain and see if it flags anything. It will show an SMTP delivery.

      I would also suggest that you go through the sticky thread and use some of the tools in there, including the Exchange Best Practises tool and confirm the server is configured correctly.

      Ensure that SMTP is running and is bound to the correct IP address and Exchange is answering. If you have AV on the machine ensure that SMTP scanning is not enabled.

        Also, check the DNS records for your domain using nslookup and make sure the MX records are correct.
