KMail 3.3 + S/MIME : some tips

[Adeodato Simó <asp16@alu.ua.es>]

  these are, briefly, the steps I have followed to get some S/MIME
  support in KMail 3.3.

    Wipe out all not needed packages:
    # aptitude purge newpg gpgsm cryptplug cryptplug-dev libgpgme6 libgpgme-dev libksba0

    Use packages provided by Matthias Urlichs <smurf@debian.org>:
    # echo "deb http://smurf.noris.de/code/debian/ experimental smurf" \
        >>/etc/apt/sources.list 

    Install required packages
    # apt-get update && apt-get install gnupg2 gnupg-agent dirmngr

      NOTE 1: gnupg2 will *NOT* substitute your gpg command, it will
      just provide /usr/bin/gpg2, which you needn't use, and some other
      commands that the programs will use internally.

      NOTE 2: the gnupg-agent package from smurf does NOT provide
      /etc/X11/Xsession.d/90*gpg-agent.

      NOTE 3: gnupg2 1.9.10+cvs-1 contains /usr/share/locale/locale.alias,
      which is also in the locales package. you'll need dpkg
      --force-overwrite.

    ===> RECOMPILE gpgme0.4 <===
    This is the sole cause for the error "this GPGME version was
    compiled without S/MIME support. Now it will because of gnupg2
    installed:
    # apt-get source gpgme0.4 && cd gpgme0.4-0.9.0
    # debuild && dpkg -i ../libgpgme11_0.9.0-1_i386.deb

  You should now see funky things in KMail -> Settings -> Configure
  KMail -> Security -> Crypto Backends -> Configure.

  I found this page useful:

  Kleopatra now works and KMail seems able to verify S/MIME messages.

  DISCLAIMER: I claim no deep knowledge of all of the above explained.
