Root is an "exposed user", in other words, mail sent by root is not  
masquaraded by default, even if other addresses would be.

Anyway, this doesn't really matter, as your ISP's mail server should  
be willing to relay your mail anyway.  You should talk with tiscali.nl  
about what else you might need to do-- perhaps setting up SMTP auth  
would let you relay through their mailservers...
