Mailserver written in Go:
Maddy Mail Server implements all functionality required to run a e-mail server. It can send messages via SMTP (works as MTA), accept messages via SMTP (works as MX) and store messages while providing access to them via IMAP. In addition to that it implements auxiliary protocols that are mandatory to keep email reasonably secure (DKIM, SPF, DMARC, DANE, MTA-STS). It replaces Postfix, Dovecot, OpenDKIM, OpenSPF, OpenDMARC and more with one daemon with uniform configuration and minimal maintenance cost. – Maddy
Hellbanning:
Selected email does not either get bounced nor go to spam. That would need *processing*, which costs *money*. Selected email is **deleted as it is received**. This is called **blackholing** or **hellbanning**. … Big email servers permanently **blacklist whole IP blocks** and delete their emails without processing or without notice. Some of those blacklists are public, some are not. – After self-hosting my email for twenty-three years I have thrown in the towel. The oligopoly has won., by Carlos Fenollosa
