Beginner Setting up Spam Assassin

[FalconChristopher]

Hi, I want to setup Spam Assassin so that any email that Spam Assassin 
flags as spam gets placed into a folder for a specific SMTP or IMAP 
email account. Then if Spam Assassin flags emails that are not spam I 
can tell it which of those emails to not place into the spam folder for 
the specific email client. Until it gradually learns which emails are 
spam and which are not.

I've done a little research and I have access with my distribution to a 
mail directory as well as the local.cf file for which configurations are 
for Spam Assassin but I don't know how to setup what I mentioned above ?

Thank You

Christopher
