advice on bodyless emails

[Richard Kimber]

I have recently been plagued with emails that have no subject or body
similar to the following:

================
>From zuvzffkne at univ-st-etienne.fr  Wed Jan 28 19:43:00 2004
Return-Path: <zuvzffkne at univ-st-etienne.fr>
Received: from pop.ntlworld.com [62.253.162.50]
        by localhost with POP3 (fetchmail-6.2.4)
        for psrwebs at localhost (single-drop); Wed, 28 Jan 2004 19:43:00

X-Bogosity: No, tests=bogofilter, spamicity=0.414283, version=0.16.3

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

These all seem to originate from different addresses.  What is the best
way of dealing with them? Teaching Bogofilter that they are spam will
presumably only work for that particular message.  Would it be better to
try to filter them out with procmail?  Any suggestions?

Thanks,
- Richard.
