Firefox and spamassassin

[Art Edwards]

I have spamassassin working on my firewall box from which I POP mail
with tbird. There are many emails that are flagged with low-level
threats by spamassassin that are not initially marked as junk by
firefox. Under Junk Mail controls in the Tools pull-down I have checked

Trust Junk mail headers set by    spamassassin

Is there a way of having any spamassassin score greater than zero
initially marked as junk?
