Stare at the headers: it's usually a very shallow impersonation. For
example, the Received headers are likely to point back to machines you've
never heard of -- or even countries.

Turn your machine off for a week and see if it stops <wink>.

Not on a well-run blacklist. This kind of spoofing is common.
