I have distribution list that where I have set Message restrictions to accept messages Only from a set of users. Some of these users have secretaries, which can send on behalf of their manager. If the manager can send to the distribution list can their secretaries send on behalf to the list as well? Or will I need to add the secretaries to list of "Only from:"?


The secretaries will be able to send to the list provided they are sending as the manager. They should not be able to send messages to the Distrubtion list otherwise! I hope this helps you out.


SendAs and SendonBehalf permissions are two different things.

  • For SendAs use, the Principal needs permission to send to the restricted DL.
  • For SendOnBehalf use, the Delegate needs permissions to send to the restricted DL.

This is what I have found regarding the subject, hope this helps:
