Return Path = my address = spam ...

Grrrrr.


My spam load has mysteriously increased of late, that is the stuff getting 
to my mail box.

After searching for an answer to this:

Date: Wed, 22 Nov 2006 10:26:11 +1100
Sndr: [email protected]
From: "Allen Fisher" <[email protected]>
   To: at@[*]
Subj: let now and your God hath he is in their hands on The
Actn: OK (from-file /home/at/.tmda/lists/confirmed ok)                 (18067)

I realised that the sender was me and the recipient was me and bugger.  The 
 From however was not!

Now I know one solution is to do something like:

headers 'Return-Path:.*[email protected]' drop

(Incidentally that filter isn't working real well because it didn't catch 
this message!)

But if I copy mail to myself for legal reasons, naturally this is a problem.


Does anyone have a solution or suggestion?
