Maddy - Composable all-in-one mail server

•    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.

Mail-in-a-Box helps individuals take back control of their email by defining a one-click, easy-to-deploy SMTP+everything else server: a mail server in a box.

Technically, Mail-in-a-Box turns a fresh cloud computer into a working mail server. But you don’t need to be a technology expert to set it up.

Flat mail representation of MimeMail is simply a KeywordList where all the keys [:txt,:html,:attach,:attach_in,:include] are used to construct the body tree of alternative/mixed/related multiparts in the body field of the MimeMail struct, and the rest of the KeywordList became the header field. Need more explanations here...

dmarc-report - DMARC Report generator

The DMARC reports are received on email attachments in XML format (compressed). I don't know a default viewer and we receive one file by day by external domain. I needed join the data and build a visual report. Copy or rename .env-example to .env and set the values to your environment.

go-msgauth - A Go library for DKIM, DMARC and Authentication-Results

•    Go

---

Why can't I verify a mail.Message directly? A mail.Message header is already parsed, and whitespace characters (especially continuation lines) are removed. Thus, the signature computed from the parsed header is not the same as the one computed from the raw header. How can I publish my public key? You have to add a TXT record to your DNS zone. See RFC 6376 appendix C.
