SpamAssassin Rating high but Mail-Spam-Filter doesn't catch it

Question

I have SpamAssassin running on my Mail-Server and Mail set to trust the server-side-spam-filter (And as Apple states SpamAssassin is compatible (even used in OS X Server)).
Most Spam gets crunched but I have some that I get over and over again although the SpamAssassin rating is set and often even above 9.
Can I somehow make Mail more sensitive to the rating?
(I don't want to use a custom rule to sort it because then the new mail sound will play for any spam as well.)

Answer 1

No, it doesn’t make sense. You may want to read Mail Help’s “Automatically processing email” article to better understand how rules work in Mail.
the rules operate before the messages are placed in any mailbox
Rules are fully applied to each message, one at a time, in the order they appear in the list. How could it be otherwise? What you say doesn’t make sense to me...
What I should have also suggested is 'stop evaluating rules' on the first rule
That would be redundant and useless. Mail stops evaluating rules for messages moved to another mailbox by a preceding rule.
Rule 2 exists only to make the sound
Problem is, it would also play the sound for junk messages not caught by the first rule.
I suggested 'To includes @' to catch all mail not filtered out by rule 1
Not sure what you mean. If you want the second rule to be applied to every message not caught by the first rule, there is an Every message condition for that.
perhaps move to inbox isn't necessary?
Not only is it unnecessary. As I said, it might cause an infinite loop that Mail cannot handle properly.
This way the spam won't trigger the sound but everything else will.
And that’s precisely part of the problem, that everything else, including junk mail caught by the built-in junk filter (which is applied after all the other rules), will trigger the sound...
