Set "Sign Messages Already Processed = no" and set the %org-name% the 
same in all your MailScanners. It uses the presence of the 
X-%org-name%-MailScanner: header to work out if it still needs signing. 
It's about the only time MailScanner uses the contents of a header to 
affect processing.

Yes. Create a file called, for example, /etc/MailScanner/domain.list and 
put this in it:

Then in the ruleset use this:
To: /etc/MailScanner/domain.list no
From: /etc/MailScanner/domain.list yes

It's not true ruleset nesting, it is just using a list of address 
patterns to save you having to write multiple rules yourself. It is 
implemented by generating a rule for every address pattern listed in 
your domain.list file. So they can be anything allowed in an address 
pattern, domain names, email addresses, perl regexps, etc, etc...
