I'm not sure that you can have that multiline echo ...
Anyway, try the following which uses sendmail -f to set the From Address..

--------------------------------------------------------------------------
#!/bin/bash
#
PERCENT=$1

FROM="postmaster at support.off"
qwf="/tmp/quota.warning.$$"

echo "Date: `date`" >> $qwf
echo "From: $FROM" > $qwf
#echo "To: $USER" >> $qwf
echo "Subject: Mailbox size warning" >> $qwf
echo "" >> $qwf
echo "You are now using $PERCENT% of your mailbox quota." >> $qwf
echo "If you reach 100%, new mail will not be delivered to you." >> $qwf
echo "Please cleanup your mailbox." >> $qwf
echo "-- " >> $qwf
echo " Your Mail Administrator." >> $qwf
cat $qwf | /usr/sbin/sendmail -f $FROM "$USER"
rm -f $qwf

exit 0
