	The same basic setup here at work running on a FreeBSD 3.3 box, I
haven't seen this problem, let's see what may be different.

	From this last log entry here it shows that you are running procmail
via a .forward, I wonder if procmail may be doing something strange. 
On the machine that I've got we're using procmail for local delivery,
not via a .forward

	Like I mentioned before, doing the same thing here, it looks like the
only difference is that you are using procmail via a .forward.  One
thing you might want to try is taking procmail out of your .forward
and see if procmail is doing something strange.
