Thanks Dave, this is of course true and I know
that the filter will run *after* a message has
already been received.

A friend of mine uses PROCMAIL and set up
a rule that works like this:

------------------ snip -----------------------

# IT unwanted newsletter
:0
* ^From:.*nted@???
{
        EXITCODE=67
}

This will execute EXITCODE 67 with Sendmail

-----
...
 *      EX_NOUSER -- The user specified did not exist.  This might
 *              be used for mail addresses or remote logins.
...
#define EX_NOUSER       67      /* addressee unknown */
...
-----

------------------ /snip -----------------------

If a sender receives 'Error 550 - User unknown'
is the easiest way to get of an unwanted spam list
even if the message really is a fake.

If the above is not possible would there be any
other way?

Best regards
