Undeliverable message to another country
I moved my email from godaddy.com to a local exchange server and now I get an error sending email to a customer in another country.
This is the error message.
"stef@mweb.co.za
vpostwall05.mweb.co.za #550-Verification failed for <djanson@gmsminerepair.com > 550-It appears that the DNS operator for gmsminerepair.com 550-has installed an invalid MX record with an IP address 550-instead of a domain name on the right hand side. 550 Sender address rejected: Domain not found ##"
Is there something I need to setup on the exchange server to allow this to send out, and then hopefully receive?

Ah - sorry - my mistake - so used to 2003.
Go to Organization Configuration
Hub transport
Send connectors
double click on the connector used to send the outgoing mails
And there you can change the FQDN on that connector
Then Restart the Microsoft Exchange Transport Service

alanhardisty, I did your update. I also updated the Receive Connector on the Edge Transport server. I then ran the SMTP diagnostics test and I came up "mail.gmsminerpair.com". Thanks.
Grandebob, I called GoDaddy and requested "reverse DNS" and they said they do not support it. However did find something about creating a SPF record to do the same. Does this sound right?

Call your ISP - your Internet Service Provider to setup RDNS .
Your ISP is the people you use to connect your company to the Internet.

alanhardesty, Ahh, I understand now I will call them.
On the other hand, I was finally able to successfully send and receive email from my customer, however I run multiple domains on exchange. I was only successful with the "gmsminerepair.com" domain email address. When I send the same receiver and email from my "pioneerconveyor.com" account it still comes back undeliverable.
These domains all resolve to the same IP. How do I get HELO to work on all my domains?
All of these domains are on the same SAN certificate.

Please post the full NDR message - would be nice to see if is your server or their server rejecting it.

Here it is:

OK, after a closer look, I did not fix the MX record host name for that domain. I just changed it and will give it a few minutes to update the DNS records.
Seems like you managed to change it before I could test - should be better now unless the recipient server caches DNS.
ASKER
Nope. That did not work. Here is the NDR msg.

The only difference I see is the HELO reply. It is "mail.gmsminerepair.com" instead of "mail.pioneerconveyor.com" though both resolve the same address. Is this causing the NDR? How can you setup 2 FQDNs for HELO?
Change the MX record from priority 0 priority to priority 10 - apparently some servers don't like a zero priority (came from Mestha - EE God!)

If the HELO reply was the problem, you would not be able to send from both addresses.
ASKER
I just set up the all the MX records in the DNS to the same address as the domain in the HELO response. I dent the troubled e-mail and have not yet received and response.
Still no RDNS setup - did you call your ISP yet?
MX's are now 10's not '0's.

I am calling my ISP now.
You told me to change them to 10's. Should I change them back?

No - 10's are good. Leave them as they are - just letting you know the world will see the 10's!
Hope the ISP doesn't keep you hanging ;-)

You speak from experience... I called then and told me to submit an email and should hear something back in 24hrs. Wooo whooo.
ASKER
I was able to successfully send the e-mail message without waiting for my ISP to setup RDNS. However I will follow through with getting that done.
Grandebob was right from the beginning so I had to give him some of the points.
alanhardesty, thank you for hanging in there with me and for your continued, immediate help. For that I give you most of the points.
