[Mimedefang] Small "Bug" in mimedefang redhat init script

[Kevin A. McGrail]

The configtest procedure in the redhat init script is needs $PROGDIR 
prepended in case mimedefang.pl isn't in the path:

i.e. line 163 should read:

$PROGDIR/mimedefang.pl $([ -n "$SUBFILTER" ] && echo "-f $SUBFILTER") -test 
 > /var/spool/MIMEDefang/configtest.out 2>&1

Not bothering with a diff.
