Mail’s Junk Mail filter continues to learn every time it processes an incoming 
message—whether or not you manually mark it as Junk (or Not Junk).
Correct it's mistakes, and it learns! The more diligent you are in training the 
filter, the more accurate it becomes.

I have not had Spam in my Inbox for a very long time, it all goes in my Junk 
Mailbox.
I do still check the "Junk" Mailbox before I empty it, just to be sure.

Mail can also check special headers inserted by a spam filter running on your 
ISP’s mail server. 
Many ISPs use server-based spam filters such as SpamAssassin or Brightmail. 
If such a filter identifies a message as potential spam, it tags it by adding a 
special header to the message, such as X-Spam-Flag or Received-SPF; you can see 
these by choosing View > Message > Long Headers.

If a message contains this header, your ISP’s spam filter—which may be more 
advanced than the one in Mail—suspects the message to be spam. As long as 
"Trust Junk Mail Headers Set by Your Internet Service Provider" is selected in 
Junk Mail preferences, Mail marks such messages as Junk Mail.


Cheers,
Ronni
