But they're to blame for not running VLANs and proper IP
filtering.  That's a sizable security risk, and an unacceptable
setup.  It would not have happened on a properly-configured
network.

The MX record, like any other DNS entry, must be hosted by the
authoritative servers.  If mydomain.com's NSen are authoritative,
then they must host the MX records.

Example:

			IN	MX 10	name.of.primary.mx.
			IN	MX 25	perhaps.a.secondary.mx.
			IN	MX 87	maybe.tertiary.too.

on the authoritative machines.  If you're not the authority, the
NS that are must have entries like the above.

If you run a DNS master, you could make the entries on your
machine and have the auth NSen slave or rsync zone info from you.
