If a user registers their key for address alice@example.com but receives a
message sent to alice+something@example.com, this message should be encrypted
as well.
- Implement delimiter support for GnuPG encryption.
- Add E2E test case for a clear text message delivered to an address with
delimiter.
- Fix minor bug: wrong configuration parameter was retrieved when logging
information about enc_domain_keymap being active.
- Add a new test input message for a new test identity, test scenario
configuration and a test key.
- While retrieving message payload, determine charset based on the
Content-Type header. When missing, default to UTF-8.
- Use more comprehensible variables names.
- Adjust logging levels.
- Use an environment variable to point at the configuration file while
strating gpg-mailgate.py.
- Unify paths: store temporary config, logs and anything else under 'test'
directory.
- Configure more tests (RSA, Ed25519).
- Add test descriptions to be shown before they're started.
