This looks suspiciously like a 'subscribed with one address, forwarding
to another' situation compouded by a confusing DNS on the recipient's
end.

Well, a quick check of MX records shows that mail.any-mail.co.uk *is*
the primary MX for downen.com.  The secondary is fallback.mail.uk.uu.net
which appears similar to the one shown above.  I'd hazard a guess that
it's attempting to take a circuitous route but mail.any-mail.co.uk isn't
set up to properly accept mail from lfallback0.lnd.ops.eu.uu.net (which,
as its name suggests, appears to be a 'fallback' server).

The website at http://www.any-mail.co.uk/ shows it's a "free e-mail
service, making use of over 18,000 domain names".  Maybe that's 18,000
chances for a stuff-up, too.  As for uu.net, well, that is (or was)
WorldCom.....good luck there.  We've had quite a few uu.net subscribers
here in Australia that had major e-mail routing problems after
WorldCom's meltdown.

Have you got *any* subscribers with downen.com, any-mail.co.uk, or
uk.uu.net addresses?
