Good point, maybe this is a little safer..:

#!/bin/sh 
MOVEMAIL=/usr/lib/emacs/20.5/i386-redhat-linux-gnu/movemail
TMP=/home/reader/spool/backup/lap.tmp
MAIL=/home/reader/spool/backup/lap.sp
if [ -s $TMP ];then
exit 1
else 
$MOVEMAIL $MAIL $TMP >/dev/null && cat $TMP && rm -f $TMP
fi

Then at least I can check it out before anything is deleted.

How can I change this (or the mail-source prescript) so that gnus tells
me if something untoward happens?
