Sounds like an outbound firewall or filtering issue?
Yeah, need an NDR sample sent out-of-band.... Unaware of it being an issue on our service. Yet?

Has anyone else seen deliverability issues _from_ us.af.mil in the last 10 days? If so, have you fixed it? We have received out-of-band reports that email sent to us gets bounced back by the us.af.mil server. No evidence of a HELO or EHLO reaching our server. Obviously it might be interesting to see the error message in the bounced email, but as the sender is not in my organization, my influence is very limited.
