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? -- Chazzozz!!
