maddy

    Composable all-in-one mail server.

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.

Note: IMAP storage is "beta". If you are looking for stable and
feature-packed implementation you may want to use Dovecot instead.
maddy still can handle message delivery business.
