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.
