You have an Exchange organization named contoso.com. All servers in the organization have Exchange Server 2010 SP1 installed. The organization contains a mail-enabled domain local group name Group1.
Users from outside the organization report that all email messages sent to [email protected] generate a non-delivery report (NDR).
You need to ensure that users from outside the organization can successfully send email to [email protected].
What should you modify for Group1?
A.
The advanced settings.
B.
The mail flow settings.
C.
The group scope.
D.
The group type.
Explanation:
By default the Message Delivery Restrictions, under the Mailflow options, are set to require that all senders to group mailboxes are authenticated locally by the server. This is not acceptable if the group will be accepting mail from external domains.
