Calling users' .mailfilter from global maildroprc

FreeBSD 4.4-RELEASE
qmail 1.03
vpopmail 5.4.0rc1
SqWebmail 3.3.5
maildrop 1.5.2

What I'm attempting to do is call a users' .mailflter from the 
domain-wide .qmail-default file of vpopmail. This is working correctly 
except for one thing: SqWebmail sets up the .mailfilter file's Maildir 
paths relative to the user's home directory. Since the .mailfilter is 
being called from the user's parent directory, maildrip tries to deliver 
the email to vpopmail/domain/domain.com/Maildir/--rather than 
vpopmail/domain/domain.com/user/Maildir.

Here's my .qmail-default:

| /usr/local/bin/maildrop .qmail-default-mailfilter

Here's my .qmail-default-mailfilter:

VHOME=`/usr/local/vpopmail/bin/vuserinfo -d $EXT@$HOST`
MAILFILTER="$VHOME/.mailfilter"
VPOP="| /usr/local/vpopmail/bin/vdelivermail '' bounce-no-mailbox"
logfile "/usr/local/vpopmail/domains/.maildroplog"
log "EXT is $EXT"
log "HOST is $HOST"
log "VHOME is $VHOME"
log "VPOP is $VPOP"
log "MAILFILTER is $MAILFILTER"

if ( $SIZE > 0 )
{
      include "$MAILFILTER"
}

to "$VPOP"

Can anyone offer suggestions, or pointers to docs, for making this work?
