smtplib.SMTP expects ASCII-only message bodies when message body is provided
as a 'str'. If we pass a 'bytes', we need to choose encoding earlier and we
do this by calling 'as_bytes' on messages with SMTP policy, which takes care
of formatting the body properly.
As a result, ISO-8859-x messages are converted to Quoted Printable and UTF-8
messages are Base64-encoded.
Testing this behaviour is tricky, because we use the same SMTP client to send
test data. For this reason, test code has become a bit ugly, but it does
exactly what we need.
- Add a dedicated configuration file for lacre.daemon.
- Implement test/daemon_test.py like test/e2e_test.py, to automate the
following procedure:
1. Start up lacre.daemon.
2. For each test case, send test message to the daemon and verify that the
output received by test/utils/relay.py contains expected pattern.
- Simplify Makefile.
- Fix indentation here and there.
In particular, move:
- test utilities to test/utils;
- unit tests to test/modules.
Also: start implementing the Lacre daemon test (just a stub for now).
