Out of curiosity, are you sending from a node you own and manage, or do you have your email hosted via a third-party (either with your branding skin on it or with the third-party's branding skin, i.e. are you "me@corp.com" or "me-corp@gmail.com")? So my employer, for instance, "has our own email" but it's just Gmail and we never have problems sending or receiving because we're piggybacking on Gmail's "This is a corporate account with several years of good behavior under its belt" trust signal.
