Which is good. Now we know there's nothing odd going on - prior to this
we had to assume.

OK, all looks perfectly reasonable.

But this is odd.

As far as I know this *should* fall back to the second MX, however...
there has been no IP-level rejection (connection refused, ICMP
network/destination/host/port unreachable or similar). If I try to
telnet to the host, my session sits there until telnet decides it's been
too long and it wants a cup of coffee, then gives up. There's nothing
from the remote end telling us that the server's dead, just silence.

I'd hazard a guess that this is where your problem lies - this isn't
really a "failure" that you could call by a name, just... silence. Now
that *should* result in trying the second MX.

What do you see if you grab one of the message-IDs you have queued and
do:

exim -d -M MESSAGEID

?
