required score vs refuse score

[Michael Worobcuk]

Hi,
I am using Spamassassin and Vexim.
In the Vexim Interface I can adjust the values :
- SpamAssassin tag score
- SpamAssassin refuse score

and in the Spamassassin userprefs-table I can insert a value for the  
required score.

What is the difference between the values "refuse score" and the  
"required score" ?
