43a0b5cb47 remail/remaild: Fix failure message
While handling an exception in process_msg() the handler triggers another
one by trying to print a undefined variable (mailfile).

Hand the mailfile name into the function. Use 'pipe input' for pipe mode.

7e4cace1e2 remail/mail: Handle dwmw2s magic evo plugin
dwmw2's evolution plugin which seems to workaround ms-exchange oddities has
another interesting format not handled by remail yet:

multipart/mixed with:
  - empty text/plain section
  - application/pgp-encrypted
  - application/octed-stream

Check for this with at least some sanity checks and morph it into a regular
multipart/encrypted message so decrypt can handle it without adding more
mess to that part.

8e6e7c2cc5 config: Introduce an enabled flag for S/MIME
This allows setups where there is no S/MIME. In some scenarios using just
GPG is fine and S/MIME might even be discouraged. Previously this required
to provide a dummy S/MIME key just to make remail happy. With this new flag
there is no need for that key if S/MIME is not required for the list.

bc2b62bdda remail: Relax the mail validation so new gTLDs have a chance to pass
These days it is common to see mail addresses from the newer TLDs that do
not always fit in two to three chracters. These are not covered by the
basic mail address validation regex.

Relax the requirement from two or three characters to just two or more
characters to covers these.

fc918a9bef remail/gpg: Use the lists private key for signing
Konstantin reported that outgoing mail from a mailing list is signed with
the default private key found in the private keyring.

That's caused by just handing boolen True into the 'sign' argument of
gpg_encrypt() while the documentation clearly says:

  sign (defaults to None)
    Either the Boolean value True, or the fingerprint of a key which is
    used to sign the encrypted data. If True is specified, the default key
    is used for signing. When not specified, the data is not signed.

Hand the list account fingerprint in if signing is enabled in the
configuration.

5e8939d9a0 remail: Make sure list configs inherit global gpg/smime
Per-list config dictionaries were always instantiated with default gpg
configuration because global gpg/smime settings were being ignored. This
change makes sure that smime and gpg options set on the global level are
inherited by list-specific configurations.

18a16b08fb remail: Fix default list-id value to conform to RFC2919
According to RFC2919, List-Id header should be in the form of a hostname
value enclosed inside angle brackets. This change does two things:

1. Fixes the default to be the list address with "@" replaced by a "."
2. Allows setting custom list-id values inside remail.yaml
3. Documents the "listid" optional setting in the manpage

d7b8db9b96 remail/mail: Handle Outlook GPG plugin proper
The Outlook GPG plugin works in interesting two variants:

  1) msg.asc or msc.gpg provided as a plain attachement
     without PGP envelope

  2) GpgOL_MIME_structure.txt contains a fully enveloped
     PGP payload with the proper headers.

Of course everything can be base64 encoded and the number of payload
sections is variable as well.

Implement the handling for #2 so it can coexist with the existing
workaround for #1.

1ed9841f76 remail/gpg: Allow specifying path to the gpgbinary to use
We want to be able to support ECC subkeys, which limits us to gnupg
versions 2.2 and above. CentOS-7 ships with gnupg-2.0, which cannot be
easily upgraded to 2.2 due to a slew of potential problems, so we
install the newer version into /opt/gnupg22 and must call it as
/opt/gnupg22/bin/gpg.

Allow specifying gpg binary path to use instead of the default "gpg" in
$PATH.
