Unknown Sender

By default, these messages are deleted and the default recipient is notified.

Optionally, you can delete the message without sending a notification.

In both cases, the deleted message can be archived additionally in the installation directory ...\SMTPIn\Error.

If messages shall also be sent if the sender was not found in the data base, "sent with this user's UMS-settings" must be chosen and a valid sender (e-mail address) must be entered.

If the sender of an outgoing message has not been found in the LDAP-data base, the permissions and sender information of the sender entered here are used.

The sending report is delivered to the original sender!
