Milestone 4 reached

With Milestone 4 reached, Husk gains some new features:

• Husk will wrap an email it encrypts into a fitting mime structure so that MTUs (Mail user agent, like Thunderbird) can display the message properly.
• Husk now can deal which attachments.
• Header protection will be used with encrypted emails.
• Husk can sign messages if you provide it with an appropriate key.
• Hush can now send itself into the background. It now understands start, stop and status.
• When building Husk from source, files for shell completion are generated.
• When listing introducers their associated domains are also displayed.

Please refer to the documentation for a full list of all features and their usage.

Status

Husk can now be used safely for pass-through mail encryption, but:

As Husk only encrypts if an authenticated certificate is available, emails with more than one recipient are only encrypted if there are certificates for all recipients - otherwise the mail will not be changed. That means that even if a certificate is available for a certain recipient, it might not be used.

This behavior will be improved in milestone 5.
