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, SIZE, DSN
- DKIM, DMARC, SPF, ARC
- 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)
