Hi

I am working on a SBS2k3 server with exchange 2003. My mail system is working for the most part however I am receiving NDR's with the error code of 5.3.0 . I know that this means that it is a permanent delivery problem where its to "other or undefined mail system". I have set up message tracking which tells me that the mail gets to "started outbound transfer of message" then delivers the NDR. Further more I hace logged onto dnsstuff.com and verified that the domain exists together with sending a mail from another site with the same op sys and exchange where it gets delivered.
Also I have downloaded winroute and repaired any suggestions which it suggested which wasnt much, where now it says that wmi is working correctly.

I am unsure what to try now from here on....does anyone have a suggestion that I could try from here on.

Many thanks

Hi,

Can you try testing SMTP to the failing domains using telnet from your server? Use nslookup to find their MX record info and then try telnet to test message delivery from your site. You should also turn up diagnostic logging on the SMTP.

Configuring Diagnostic Logging for SMTP
http://technet.microsoft.com/en-us/library/bb124167.aspx

This command will show you their MX records and IP addresses that your server is resolving via DNS.
nslookup -type=mx theirdomain.com

Hi

Having difficulty using nslookup to get mx record details...I can get into nslookup....I can obtian my default server. I can switch my default server. I can run "set q=mx". I cant seem to get any futher. I am looking for the mx  record info for www.entemp.ie. What comands do i need to type to obtain this.

Secondly, I have been able to use the telnet. I can send and rec smtp from the host server to the destination server (www.entemp.ie) where i am receiving replies "sender ok" and "250 / 2.1.5 codes back"

Can you tell me why i need to obtain the mx record info, plus what i do with it and how to obtain the mx record in nslookup please?

Regards

nslookup -type=mx entemp.ie

will give you the mx records. You normally use those to get the IP address for telnet. Do all mails from your site to this domain fail? They only have one MX record so if something happens to that box you will recieve NDR's.

If you can send via telnet then from your server then it should work via Exchange also.

Hi
1)when i type this command "nslookup -type=mx entemp.ie" i get unrecognised command....what do you think i am doing wrong?

2)Do all mails from your site to this domain fail?                yes, but only internally in the lan. Anything sent outside the lan go through!

3)They only have one MX record so if something happens to that box you will recieve NDR's.- does this mean you have look them up?

Regards

1. I don't know what would be wrong - try these steps - http://technet.microsoft.com/en-us/library/bb123686.aspx

2. So you cannot send e-mails to this domain ever from your Exchange install?

3. Yes. I did an nslookup for their domain and found only one record which is accepting mail this morning.

Can you post the complete NDR (just substitute your private details with something like server.yourdomain.com user@yourdomain.com etc

2. So you cannot send e-mails to this domain ever from your Exchange install? Certainly not in the last three weeks...before that I would have to check with the client!

The entry here "SORBS" makes me think that they may be using some kind of SPAM blacklist filtering that your IP or the ISP's range of IP's may be on.

Enter your external IP address here to check if you are on any blacklists - http://www.mxtoolbox.com/blacklists.aspx

You need to have your ISP or you need to make the request to the blacklist admins to have your IP removed or have the external company place you on w hite list so that you can send successfully.
