We have a few distribution groups setup that people use as shortcuts for e-mailing large groups of employees. For example, [email protected] sends to all the users in the admin department. Anyway, is there a way to set those lists to ONLY receive mail from our domain? So someone from outside our organization would never be able to e-mail those addresses? thanks Jeremy Author Posts Viewing 1 post (of 1 total) You must be logged in to reply to this topic.
