Change in spam processing - resolved

[Stephen Davies]

Turns out that the amavisd update installed last month reset the default spam 
filter to spam assasin and that this update came into action yesterday.  (Not 
sure why.)

Modifying amavisd to use bogofilter again and restarting amavisd returned 
things to normal.

Cheers,
Stephen
