I'll get someone to contact Ford and see what they are running. From
google it looks like Exchange. Is this a known bug with Exchange? If so
I think there's bigger problems than messagelabs :)

As it obviously checks only the first MX record if there are A records,
and if there are none it rejects it. This while there are AAAA records
on the first MX, and even A records on the remaining MXs. Thus a proper
fix would already be to check the other MXs and of course to check for
AAAA too ;)
And that affects all customers at messagelabs, thus if somebody can pass
that along to them to fix it, that would be great ;)
Oh and of course the check is also there for postmaster@ thus no way to
tell them through that route.
Greets,
