Installation instructions

   1. Go to [WWW] http://ixhash.sf.net and download the current code. Within
the archive you find a folder named 'iXhash', there again you find two
files, iXhash.cf and iXhash.pm
   2. Copy 'iXhash.pm' and 'iXhash.cf' somewhere where SpamAssassin can
access it - like /etc/mail/spamassassin.
   3. Edit the first line of iXhash.cf (the loadplugin line) to reflect where
iXhash.pm is. You may also want to change some other options which are
explained in the comments
   4. Adjust scores. You might want to de-/increase the scores given in the .cf
file first to see if there are too many FPs. You might even want to do some
mass checking...if you do, let me know the results
   5. Run 'spamassassin -D IXHASH < iXhash.eml', where 'iXhash.eml'
is a file contained in this archivecontaining an email including headers. 
The output (on STDERR) should show you wether the plugin is being used.
More importantly it should trigger on generic.ixhash.net - the mail's hashes
are permanently listed there.
   7.  restart spamd/amavisd/whateverDaemonUsesSpamAssassin
