emacs-extend-smime 3.3 Improved S/MIME support for Gnus in Emacs

ExtendSMIME is designed to be used with Gnus in Emacs. It enhances DefaultEncrypt (emacs-default-encrypt) to support S/MIME (Secure/Multipurpose Internet Mail Extensions) via LDAP (Lightweight Directory Access Protocol). Before a message (e.g., email) is sent, ExtendSMIME searches for missing certificates via LDAP and imports them into gpgsm. When certificates for all recipients are available, DefaultEncrypt automatically encrypts the message. For details and instructions on how to use ExtendSMIME, please refer to the home page or read the comments in the source file, jl-smime.el.
