Apologies in advance for what is undoubtedly going to turn out to be a "D'oh!" 
error on my part, but I'm running out of ideas here.

I'm trying to block incoming mail from French snowshoe spammer "multi-fax.fr", 
who sends mail from a range of IP addresses and changes domain names every day 
to try to avoid detection.

In my IP blacklist file at '/home/vpopmail/spamdyke/ip-blacklist', I have 
entries:

195.43.150.170
195.43.150.171
194.43.150.172

and so forth. The file contains just 40 lines (so I'm not hitting any upper 
limits on file size).

My spamdyke configuration file at '/etc/spamdyke.conf' contains the line:

ip-blacklist-file=/home/vpopmail/spamdyke/ip-blacklist

The configuration file does not contain any other 'ip-blacklist-file=' entries, 
and 'ip-blacklist-entry' is commented out.

Spamdyke itself is being invoked with:

/usr/local/bin/spamdyke -f /etc/spamdyke.conf …

and I know that the correct config file is being read, because it's creating 
its graylists at the appropriate place. Graylisting and blacklisting work 
splendidly, by the way.

However, the French are still getting through. Here's a 'Received' line from a 
message:

Received: from mx.lirmat.net (195.43.150.172)
  by mail.mydomain.com with SMTP; 12 Jan 2012 03:15:02 -0500

and here's what the logs have to say about it:

/var/log/maillog:Jan 12 03:15:02 s1 spamdyke[16941]: ALLOWED from: 
[email protected] to: [email protected] origin_ip: 195.43.150.172 
origin_rdns: mx.lirmat.net auth: (unknown) encryption: (none)

I was running Spamdyke 4.1.0, I've just upgraded to Spamdyke 4.2.1.

Can anyone think of a reason why IP blacklisting might not be working?

Thanks for any help or suggestions,

Angus
