Question : Email rejected by Lotus Domino server

Hi Everyone,

I'm having problem with my Lotus Domino 8.0.2 and Exchange Server 2007 mail connectivity,
I cannot send and receive email to and from both system :-|

here's the error message:

from the Domino Console:

13/05/2010 08:48:04 PM  SMTP Server [0240:0008-0DC0] Connection from ExcServer01.domain.com rejected for policy reasons. Connecting host is denied in your configuration.
13/05/2010 08:48:04 PM  SMTP Server: ExcServer01.domain.com (10.2.2.4) connected
13/05/2010 08:48:04 PM  SMTP Server: ExcServer01.domain.com (10.2.2.4) disconnected. 0 message[s] received

from the client outlook NDR:

Domino802.domain.com #554 Mail from [email protected] rejected for policy reasons. ##

Any help would be greatly appreciated.
Thanks

Answer : Email rejected by Lotus Domino server

There are at least 4 questions to investigate:
- Domino incoming
- Domino outgoing
- Exchange incoming
- Exchange outgoing
- and then the addrressing from one server to the other

Let's attack them one by one, to avoid a lot of confusion. Incoming first:
- does Domino receive incoming mails from the Internet?
- what is the full mail address of a person?
- what is the server's name in the DNS?
- what is the server's domain name in the Configuration document and/or in an Internet Site document?

You might restart the Router to see whether it's correct.

From the logs above, I assume that you defined the Exchange server as smarthost, and that the Domino server doesn't consider itself to be the endpoint for the testmail it received, which is the reason why that incoming mail is immediately transferred to Exchange (transferred, not returned). And then it gets in a loop, probably terminating after 30 hops or so.

What is the status of this question, any progress these last few days?
