Using backports after upgrade

["John Fleming" <john@wa9als.com>]

Hello - I was running Sarge with SpamAssassin upgrades from backports.org. 
Then I upgraded to Etch.  I have backports in my sources.list, but I don't 
seem to be getting SA updates.  (My SA is 3.1.7, and latest seems to be 
3.2.3)

Is there something about my upgrading from sarge to etch that could've 
affected this?

Thanks - John
