[Beds] Mail server spoofing problem

[Lee Larcombe]

Hi all

I have a problem with my domain being used as a spam return address - I keep
getting undelivered mail messages like the one below:

======================================================

This is a multi-part message in MIME format.
======================================================

My domain is larcombe-it.co.uk but the server hosting that domain (with a
mailserver) is at 217.160.223.183. The mailserver is set up to not relay
anything but a couple of domains hosted on the server - larcombe-it.co.uk is
not even one of them.

I assume someone is using my domain as the return address on their spam
emails. Has anyone else had this before? I can't think of a solution other
than just treating these bounce-backs like spam and filtering them out.

Any ideas?
