I recently spoke with some military IT guys and they stated that the military strictly prohibits external emails coming into .MIL inboxes. Supposedly their .MIL email address is only for internal communications and should not be given out for external communication.

Does anyone currently exclude .MIL or .GOV email addresses from your Sendable email lists? Do you allow them to come into your database & send to them?

We have a few thousand .MIL email addresses on our database. Should I start excluding the .MIL addresses. (It's not like it's easy to get in the inbox, as most of the time military filters catch external emails)
