I am running exim4 heavy on a Sid box.

How do I do this obvious task? In exim? I have fail2ban as well but this is
not catching this one.
You could try this as root :
# cd /etc/exim4
# touch local_host_blacklist
# touch local_host_whitelist
# touch local_sender_blacklist
# touch local_sender_whitelist
# chown root
# chmod 640 local_*
I've created these files on my Debian Lenny box and they work very well.
For the 'local_host_blacklist' file I add entries such as :
For the 'local_sender_blacklist' I add entries such as :
In the above example the last entry would be an exception and would not
be blocked. Alternatively I could add that entry to
'local_sender_whitelist' for the same effect.
Also check out this web page for some really in-depth examples of spam
filtering with Exim :
When trying out new filters you can use 'warn' instead of 'deny' which
will just add a header to the email message rather than reject it at
SMTP time. The header inserted is the contents of the 'message' line :
message = X-Spam-Header1: This mail failed on spam test 1.

Hope this helps.
