I have the following as the last rule:

if anyof (header :contains "x-spam-flag" "YES", header :contains 
"subject" "*****SPAM*****")
{
     fileinto "INBOX.Junk";
     stop;
}

It seems to fire not only when mail is first retrieved, but if a message 
is moved back into INBOX (so it moves back to Spam). Any suggestions on 
how to make it fire only on initial processing?
