Qmail-qfilter - bogofilter - size/time limitation?

[Mcclure, Barry]

 Gentlemen,

	I'm trying to take advantage of qmail-qfilter and bogofilter to
filter spam.  It seems there a size limit ( not really size but appears
to be time).  Without any modifications to the code, it doesn't appear
that qmail-qfilter is waiting on bogofitler to finishe processing large
messages.. So all I end up getting through the system is  the envelope.

Anyone have any ideas? 

Thanks
Barry
