Hi!

There are two Exchange 2K server in one org, Ex1 and Ex2, in the same routing group. There was no problems, but suddenly, Ex2 is not able to receive from anybody, but able to send email to outside and Ex1. When I sent email to an account located on Ex2, I got this message.

CAUSE
An incorrect column header is used when importing distribution lists (DLs) into the Microsoft Exchange Server Directory.
RESOLUTION
To resolve this problem:
Do not place a single mailbox in the Accept From DL property, which is intended only for DLs. For a single mailbox, use the Accept From property instead.
MORE INFORMATION
Delivery restrictions to define who can send to a DL can be assigned by using two properties: Accept From and Accept From DL. These two properties can be specified as column headers in an import file. Both of these properties are multivalued (can hold more than one value, each value separated by %). Accept From is used for single mailboxes, while "Accept From DL" is used to specify DLs. If you place a single mailbox in the property intended for DLs, you will receive the error message above.
