fixed code

[Adam Shostack <adam@bwh.harvard.edu>]

	The procmail stuff I sent yesterday was slightly broken.  It
seems that keyservers respond well to 'mget 36E61FB1', but not 'get
36E61FB1'

	To auto retrieve keys, use these two procmail recipies:

# auto key retreival
:0BW
* -----BEGIN PGP
KEYID=|/usr3/adam/bin/sender_unknown

# I have an elm alias, pgp, points to a keyserver
:0ac
|elm -s"mget $KEYID" pgp


sender_unknown

#!/bin/sh
# sender_unknown returns a keyid, exits 1 if the key is known
OUTPUT=`pgp -f +VERBOSE=0 +batchmode  -o /dev/null`
echo $OUTPUT | egrep -s 'not found in file'
EV=$? 
if [ $EV -eq 0 ]; then 
	echo $OUTPUT | awk '{print $6}' 
fi
exit $EV
