**Note: This project is in early development.**

Lindenii maild is an email server.

Contemporary email servers like [Postfix](http://www.postfix.org/) and
[OpenSMTPD](https://www.opensmtpd.org/) generally work, but setups become
rather complex when other necessary software such as
[Dovecot](https://www.dovecot.org/) and [OpenDKIM](http://www.opendkim.org/).
It is also notoriously difficult to configure these servers.

Lindenii maild is an email server designed for the Lindenii project. It
implements basic functionality for a working email server in one software
package.

We attempt to implement:
* SMTP to send and receive mail
* IMAP to let users interact with mailboxes
* DKIM, SPF, and DMARC authentication
* Basic spam filtering
* A UNIX domain socket protocol for integration with mailing list and forge
  software
* [MTA-S2S](https://www.rfc-editor.org/rfc/rfc8461)
* ESMTP extensions: [8BITMIME](https://www.rfc-editor.org/rfc/rfc6152.html),
  [SIZE](https://www.rfc-editor.org/rfc/rfc1870.html),
  [DSN](https://www.rfc-editor.org/rfc/rfc3464.html),
  [SMTPUTF8](https://www.rfc-editor.org/rfc/rfc6531)


We may consider:
* [RFC2136](https://www.rfc-editor.org/rfc/rfc2135) for dynamic DNS updates
* [DANE](https://www.rfc-editor.org/rfc/rfc6698)

Note that we may choose to not *completely* implement protocols listed above.
For example, SMTP relaying and gatewaying will not be implemented as they are
irrelevant today.
