# Lindenii Mail Daemon

None of Postfix, OpenSMTPd, and maddy really suit my taste for a mail daemon,
so I'm trying to write my own.

I also want a simple mailing list manager, but they're all rather difficult to
set up correctly. IMO it'd be easier to integrate it into the SMTP daemon.

## Plan

**Implemented:**

- Receiving mail, SMTP side, with STARTTLS

**Future:**

- ESMTP: [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)
- DKIM, DMARC, SPF, [ARC](https://www.rfc-editor.org/rfc/rfc8617.html)
- Receiving mail and mailbox synchronization via a custom protocol
- Sending mail, outgoing side, with STARTTLS
- Sending mail, incoming side, with TLS
- A UNIX domain socket protocol for integration with mailing list and forge
  software (might be called the Lindenii Mail Delivery Protocol)
- Receiving mail, IMAP side, with TLS (far future)
