NAME
       PGPsendmail - drop-in wrapper to	 sendmail  to allow PGP encryption

SYNOPSIS
       pgpsendmail [ args ]

DESCRIPTION
       The  pgpsendmail	 programme  is	a drop-in wrapper to the standard Unix
       sendmail	 programme. pgpsendmail may operate in two basic  modes.  Each
       of these is described below:

       If  the PGPPATH environment variable does not exist, the real  sendmail
       programme is executed with the same command line arguments.  Hence,  it
       is  quite  safe	to  move  the  original	 (real)	 /usr/lib/sendmail  to
       /usr/lib/sendmail.real and place PGPsendmail as /usr/lib/sendmail since
       the  system  startup scripts (/etc/rc*) should not define PGPPATH.  The
       operation of sendmail as a daemon is not affected. Also, users  who  do
       not  use	 PGP  are  also completely unaffected (as they will not have a
       PGPPATH environment variable).

       If the PGPPATH environment variable does exist, PGPsendmail will	 check
       all  recipients	in  the	 message  header (marked by "To: ", "Cc: " and
       "Bcc: " keywords) to determine if they have a PGP  public  key  in  the
       senders	public	keyring.  By  default, if all recipients have a public
       key, the message is encrypted for all recipients prior to transmission.
       The  message  is	 actually  transmitted by the use of the real sendmail
       programme.  If one or more recipients does not have PGP public key, the
       message	is not encrypted.  PGPsendmail extracts the Email address of a
       recipient when determining if a PGP public key is available.

DEBUGGING
       To enable verbose debugging output from PGPsendmail,  create  the  file
       $PGPPATH/PGPsendmail.debug.   Upon   each  Email	 you  send,  the  file
       /tmp/PGPsendmail.debug.<UID> will be over-written with a log  for  that
       message.

FILES
       $PGPPATH/pubring.pgp	     the users' public keyring file
       $PGPPATH/randseed.bin	     the seed file for PGP
       $PGPPATH/PGPsendmail.config   the users' configuration file
       $PGPPATH/PGPsendmail.debug    enable debugging if exists
       /tmp/PGPsendmail.debug.<UID>  debugging output file
       pgpsendmail/doc/README.PGPsendmail
				     distribution README (has more info.)

BUGS
       PGPsendmail  doesn't work with UCBMail and NeXTMail on the NEXTSTEP. It
       does work with Pine and Rnmail.
