Error 554 message returned in an SMTP email bounceback

Problem:

Customer was getting the following errors from their Domino SMTP mail server when sending emails via the Email Report Server:

---

03/25/02 08:55:23: Mail from root@linux.mylastname... 03/25/02 08:55:24: SMTP Host did not acknowlege MAIL FROM command. [554 Mail from root@linux.mylastname rejected for policy reasons. ] 03/25/02 08:55:25: Mail transfer failed, reason: SMTP Host did not acknowlege MAIL FROM command. [554 Mail from baduser@malformed.address rejected for policy reasons. ]

This is what the Domino Log says: 03/25/2002 07:35:19 AM SMTP Server [01F6:002D-028C] Mail from root@linux.mylastname rejected for policy reasons. Domain not found in DNS. 03/25/2002 07:35:20 AM SMTP Server [01F6:002D-028C] Mail from baduser@malformed.address rejected for policy reasons. Domain not found in DNS.

Solution:

This problem should be able to be resolved by making the following changes on the Lotus Domino server and then restarting the Domino server.

1.) Start the Domino Administrator program.

2.) Go to the "Message/Messaging Settings" tree pulldown in the administrator window. On the right side window you will see the "Messaging Settings" window.

3.) From the "Messaging Settings" window Click the "Restrictions and Controls" tab and then click the "SMTP Inbound Controls" tab.

4.) Change the "Verify Connecting Host Name in DNS" setting to "Disabled".

5.) Optionally you can also change the "Verify sender's domain in DNS" setting to "Disabled".

6.) Save the settings by clicking the "Save and Close" button.

7.) Shutdown and restart the Domino Server.
