Let me answer my own question, after i've taken a look at the code.

If sender domain is in the list specified in the setup, mail gets the 
KNOWN_SENDER symbol, which has a default score of -1.

It sender domain is not in the list, it gets the UNKNOWN_SENDER symbol, 
which has a default score of 0.5.

Both the INC_MAIL_KNOWN_GLOBALLY and INC_MAIL_KNOWN_LOCALLY symbols are 
added in cooperation with the replies module, and also has a default 
score of -1. (I'm guessing these check on the whole e-mail, not just the 
domain)
