setting required_score between each email message test?

[Joe Flowers]

Is there a way to set the required_score "on the fly" between each email 
message test?

I tried changing the required_score in /etc/mail/spamassassin/local.cf 
but it is unsurprisingly not rescanned/reloaded between each message 
that is tested. It would really be cool (not to mention extremely 
helpful) if this could be done.

Thanks!
