Thanks for the answers again.. and Holger for the rules

I put the file in /usr/local/etc/mail/spamassassin/
If i make a mistake like you said spamassassin --lint indeed barks
spamassassin --lint
Jun 13 12:25:05.692 [72537] warn: config: SpamAssassin failed to parse 
line, no value provided for "header", skipping: header whatever
Jun 13 12:25:06.793 [72537] warn: lint: 1 issues detected, please rerun 
with debug enabled for more information

So spamassassin reads the rule

Mailscanner --lint does not show me much about spamassassin.
In the directory where I have the file there is also a 
file for the FuzzyOCR rules and that gets laoded also.

I will look and see if it all works now.
