682de14630 Split the code into smaller modules
Introduce modules:
- lacre.transport - for actual delivery via SMTP
- lacre.smime - to take care of S/MIME stuff

Implement lacre.transport.SendFrom class that does a almost exactly the same
thing as the original send_msg function, but without using global variable to
store original message sender.

class RecipientList to wrap such pair of lists.

d342f206de Handle messages as EmailMessage
In the daemon, specify policy as SMTPUTF8.  That sets the deafult message type
to EmailMessage.

EmailMessage class is richer, including support for Content Managers, giving
it the capability to properly handle textual data and its encodings.

Also: add another contract test.

  manually.

5e408259c0 Start using Content Manager
Also:
- Pass text to Popen in GnuPG (used to be bytes).
- Make is_payload_pgp_inline type-agnostic (str / bytes).

d2ed4a9cee Make test reports more readable 2023-05-08 22:17:01 +02:00
94e22caf8e When encryption fails, revert to cleartext delivery
When GnuPG refuses to encrypt a message (e.g. when key has expired), record
information about the failure and send to logs, then deliver cleartext.  This
way we won't bounce email that could be delivered without encryption.

Also: add more E2E tests.
