Syntax for per domain signatures

[Max Kipness]

Hi,
 
I've been looking back at some older posts on this, and can't seem to
find the right answer. Some of the older posts refer to a config file
that no longer seems to have the same options.
 
I'm trying to configure MailScanner to append a different signature for
different domains.
 
So far I attempted to add:
 
Sign Clean Messages = %rules-dir%/sig.html.rules
 
And then in this rule file:
 
From:    *@domain1.com    /etc/MailScanner/reports/en/domain1.sig.txt
 
FromOrTo:    Default    no
 
This gives me a syntax error, plus how will it know to apply an html or
txt signature?
 
Can some one please give me some pointers or point me to some info on
this.
 
Thanks,
Max
