BCC a mailbox when mail is “Sent from” a different address

We have several general mailboxes (ex support@ourplace.com, support2@ourplace.com) that several client service reps monitor and then send from. They each have their own profiles that open those mailboxes in addition to their named mailboxes. They would like to have all email sent from those accounts BCCed to a manager. Is this possible? I would rather not have to sit down at each user’s machine and manually create a rule in their Outlook profile.

Thanks!
