Name duplication is causing a distribution list to take priority in accepting mail delivery for the name. How do I fix this issue?
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 firstname.lastname@example.org 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 email@example.com
Mail sent to firstname.lastname@example.org is now sent to email@example.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.
