How do I fix this name duplication in distribution lists?

Issue

Name duplication is causing a distribution list to take priority in accepting mail delivery for the name. How do I fix this issue?

Solution

Only an administrator can create a distribution list, and is responsible for preventing the creation of distribution lists (DL) and user mailboxes that have the same name. Always check for the existence of a user of the same name before creating a DL.

In order for the user to receive mail, they must be a member of the distribution list. For example, a user named test is created using the following commands in the CLI:

Dns Set domain mail.xxx.com

User Add test <testpasswd> <fullname for test> Mailbox Add user.test

Mail sent to test@mail.xxx.com is delivered to the user.

A DL named test is then created that expands to some other address (for example, other):

Dl Add testdlentry Add test other@yyy.com

Mail sent to test@mail.xxx.com is now sent to other@yyy.com.

To add a user mailbox with the same name to the distribution list, use the following command:

Dlentry Add test test

Mail is now delivered to both the user and the distribution list.
