Can you block certain users from sending to an alias?
Question asked by Adam Kenny - 7/31/2015 at 10:20 AM

We have an all user alias that forwards mail to everyone in our domain.  Is there a way to specify who can send to this?  We only want managers to be able to send to the agency wide address.

You can do this with a mailing list instead of an alias, and limit who can actually post to the list that way.  You can set the list to allow anyone to post, subscribers only to post, or moderator only to post.  If you allow, for example, only subscribers to post, you can then enable the poster whitelist and set only the ones (selected from the subscriber list) allowed to post in that list.

Adam, another option that I have tested and works is to create a domain content filter using "From specific addresses" and "To specific addresses" as the filter options. In the "From Address" set it to "Does Not Match" and enter the addresses of each manager; in the "To Address" set it to "Matches" and enter the alias address.  Then choose the appropriate action to perform if anyone except managers send to that alias (e.g., delete message).

Also, if you do not have the alias set as internal only, I would also set that so that external users cannot send to that alias address.
