Group properties - Delivery Restrictions tab
Use this tab to apply email restrictions to this group. You can manage the list of objects (users, contacts, groups) from whom this group can and cannot receive emails.
By default, no object is added to the Accept from and Reject from lists, which indicates that the group can receive emails from any object. However, when you specify an object in the Accept from list, the group will receive emails from that object only.
A scenario can be as:
If you want the group to receive emails from all except one member (Member A) of a group (Group A), add Group A to the Accept from list and then add Member A to the Reject from list.
Accept from
Shows the objects that can send emails to the group.
Reject from
Shows the objects whose emails will not be delivered to the group.
Add
To add an object to a list, click Add in the respective area. Enter a search string to locate the required object, or click Advance to use the Find Dialog Box for performing a search.
Remove
To remove an object from a list, select it and click Remove in the respective area.
