If you do indeed have a Cisco appliances in front of your mx you'll need
to find a way to tame that - perhaps simply open a 'hole' on port 25

JFWIW, I did not see a problem reaching either of your mx'en from a
FreeBSD box in a HKG data center.
But the US Gov is another matter.... they *might* even have to manually
whitelist your <domain>.<tld> or at least <tld>.
