 3Maddy Mail Server implements all functionality required to run a e-mail
 4server. It can send messages via SMTP (works as MTA), accept messages via SMTP
 5(works as MX) and store messages while providing access to them via IMAP.
 6In addition to that it implements auxiliary protocols that are mandatory
 7to keep email reasonably secure (DKIM, SPF, DMARC, DANE, MTA-STS).
 8
 9It replaces Postfix, Dovecot, OpenDKIM, OpenSPF, OpenDMARC and more with one
10daemon with uniform configuration and minimal maintenance cost.

12**Note:** IMAP storage is "beta". If you are looking for stable and
13feature-packed implementation you may want to use Dovecot instead. maddy still
14can handle message delivery business.
