As i said in the original post, i tried setting a few points to it and 
it would mark it as spam and not check via spamassassin at all.

Could i just build a ruleset like this:

Check Watermarks With No Sender = rules/check.watermarks.rules


From:  *.google.com   no
From:  default  yes

mail comes from hostnames similar to this: 'qb-out-0506.google.com'

Sould this work?
Thanks
