I have seen this at one of our schools. In our case it was because their spam filter sees the from address of [log in to unmask], and does not recognize our mail server as a valid sender for their domain. We modified the from address to not be from their domain, and it now happily accepts the mail. We instead set the Return-Path and Reply-To to their domain.
