#  pgp-send
#
#  This lets you set up mail addresses like "vac+eric" so you
#  can send encrypted mail without any extra work.  To use this add 
#  lines like the following to your .maildelivery file:
#
#  Addr vac+eric      pipe ? /usr/vac/pgp/pgp-send eric@foo.bar.baz
# 
#  The "vac+eric" is my alias for this person.  The eric@foo.bar.baz
#  is both the mailing address and what PGP uses to find the key.
#  /usr/vac/pgp/pgp-send is the full pathname for this script.  
#
#  I could also use my mailer to make an alias of "eric" that
#  expanded into "vac+eric" - you probably can too.
# 
#  This script assumes PGPPATH is set and pgp is on your PATH.
#  If not, either fix that, or add a "cd" to that directory.
#
#  Note that the unecrypted mail will be on your machine a little 
#  longer this way, so this is a bit less secure than encrypting the 
#  mail by hand.  However, this is a short period, and if your 
#  machine's security is broken they could have read your mail as you 
#  wrote it. 
#
#  With this, someone would need to do some "breaking and entering" 
#  to get at your mail.
