Why not just block it? Anyone who's using such a system deserves what they get. Oh, and report messagingengine.com as sending spam to someone like SpamCop while you're at it. Bearing in mind that it could be a virus with a forged from of main-admin@lists.alug.org.uk and I think you'll see where I'm coming from.

Hi all,
The list admins are getting lots of messages saying this:-
From: Mail Sieve Subsystem postmaster@messagingengine.com To: main-admin@lists.alug.org.uk Subject: Automatically rejected mail
It looks like someone has subscribed to some kind of filtering by messagingengine.com, which means for every mail that goes to the list the main-admins get a reject notice. If by any chance you know who is using this system then if you can let me or them know that would be great, (or indeed if you are that person and are reading this mail elsewhere then please make it stop!). Any (quick+easy) suggestions of how to track down the person whose mail setup is causing these would be most useful.
Oh, and messagingengine.com sucks, as going through the headers I can't find any info on which email address the mail was destined for in the first place as it appears to only look reference the body of the email and not the envelope or delivery addresses :(
Thanks Adam
