Critical Error[8.51] - BCC Recipients receiving NDR Messages

Post by aix »

Hello,

we have a very urgent Problem:

If someone is sending an E-Mail to himself and CC or BCC Recipients - the NDR Message will be sent to every CC or BCC Recipient with the same Domain the unavailable Mailbox comes from.

For Example:

-------------
FROM: test@ab.de
TO: test@ab.de
CC or BCC: 1@xyz.de;2@xyz.de;3@xyz.de;4@aaaaaa.de
------------

If 1@xyz.de is not available, the NDR Message will be sent to test@ab.de, 2@xyz.de and 3@xyz.de

Any Idea how i can solve this Problem?

Thanks!
