- Add a footer to each mail resulting from a split into an encrypted and
an unencrypted version. The footer contains the recipients of the mail
which are excluded in the corresponding stream.
- Move the construction of the `HuskContext` to the `mail`
milter-command, as `helo` is used by scrapers to detect mailservers.
- Use `CertD::trust_root()` to get the trust root - it creates one if no
root can be found.
- Add `chrono` dependency.
- Introduce option `--background` for `daemon start` to send the new
process into the background.
- Implement a `ProcessDescr` which identifies a Husk process. This pays
attention to the possibility of a rollover of the process ids.
- Implement `daemon status`.
- Implement `daemon stop` which sends `SIG_INT` to a running Husk
process.
- Husk now not only encrypts outgoing emails (if possible) but also adds
a signature.
- Rework the internal handling of the signing key.
- Integrate the signing into the workflow of the daemon.
- Add a configuration option for a subject replacement.
- Move the content of what was stored in log4rs.yml into the main config
file, so that there is just one file to parse to get the complete
configuration.
- Create the global switch `--home` to pass/overload the value for
SEQUOIA_HOME in the configuration file.
