I would be happy then :) -> .de

This might be true on a webpage or any other things. With nntp, you
have the xover command, which will give you MID, From and some other
headers, but not the Reply-To: header and not the body. Getting the
whole article is much more expensive (whole headers + body). Therfore
some usenet user (de.ALL at least...) are using a
'read_about_once_a_month@domain.de' in their From: and a frequently 
read address in the 'Reply-To:'.

-> Spammers (mostly) get the 'not read' address, anybody, who wants to
mail you privatly after reading your article will get the Reply-To:

Anyway, I don't mind anymore with SpamAssassin...
