20: In recent email to me you write:
21: >Hi, folks! The 2.3 release of PGP is coming, as they say, Real Soon Now.
22: >If you have any changes you'd like made to scripts in the contrib part
23: >of PGP 2.2, now is the time to send them in.
24: >
25: >If you want to start any work for inclusion in the release, it's
26: >needed in roughly a week ("roughly" means maybe a day or two less!),
27: >but write and I'll keep you informed.

29: Colin,
30:
31: I don't know what the latest version I sent you contains, but here is
32: the latest of what I am using. Also, I would like to ask if the pgp
33: maintainers have made the signal mods I have suggested repeatedly on
34: the alt.security.pgp group: namely, if the interrupt or quit signals
35: are ignored on entry, then pgp leaves them ignored. This permits running
36: pgp as a background task under Unix. If they have not put these changes
37: into 2.3, let me know and I'll send the diffs to you. They are very
38: straightforward, simple and noncontroversial, and I'd like to see this
39: made the standard.
40:
41: Here is my latest version of "pgpmail" the script which takes the
42: place of the standard mailer in "mailx" to perform in-line encryption.
43: I have dropped bourne shell support entirely -- this now requires ksh
44: to run:
45: =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
46: # This ksh script is invoked by adding the line "set sendmail=pgpmail" to your
47: # .mailrc file. mailx then invokes pgpmail instead of /bin/mail to deliver
48: # email. This script checks whether encryption, a signature, or both are
49: # specified, and automatically performs whatever is required.

96: Here is a copy of "pgpm", which I use to decrypt pgp mail I receive. To use,
97: just pipe the encrypted mail message to "pgpm" and it will ask the questions,
98: decrypt it, and remail the decrypted version back to you. You can then delete
99: the encrypted version and do what you like with the plaintext mail msg:
100:

103: # make sure stderr comes out on screen, to undo vi bogosity
