Enable the alternate from feature in mail-in databases

Use a Mail Settings policy to allow users of any mail-in database (shared mail file) to which the policy applies to send messages from alternate addresses.

A policy avoids the need to enable the feature on each shared mail file. This features requires the V12.0.2 pubnames.ntf and mail12.ntf design.

From a Mail Settings policy, click Access and Delegation > Access to Your Mail & Calendar. In the Mail file delegation section, select Enable Alternate From Feature for Mail in Database. Optionally, to allow internet addresses to be used automatically, select Allow automatic use internet address of Mail-in database as sender.
