-The chatmail core library implements low-level network and encryption protocols,

-We provide reproducibly-built `deltachat-rpc-server` static binaries
-that offer a stdio-based high-level JSON-RPC API for instant messaging purposes.

-The following protocols are handled without requiring API users to know much about them:

- secure TLS setup with DNS caching and shadowsocks/proxy support

- robust [SMTP](https://github.com/chatmail/async-imap)

-
- safe and interoperable [MIME parsing](https://github.com/staktrace/mailparse) 
-  and [MIME building](https://github.com/stalwartlabs/mail-builder).

- security-audited end-to-end encryption with [rPGP](https://github.com/rpgp/rpgp)
-  and [Autocrypt and SecureJoin protocols](https://securejoin.rtfd.io)

-# Request editing
-
-To request recipients to edit the text of an already sent message,
-the messenger MUST set the header `Chat-Edit`
-with value set to the message-id of the message to edit
-and the body to the new message text.
-
-The body MAY be prefixed by a quote
-and the emoji "✏️" directly before the new text.
-Both MUST be skipped by the recipient.
-
-Receiving messengers MUST look up the message-id from `Chat-Edit`,
-replace the text and MAY indicate the edit in the UI.
-
-The new message text MUST NOT be empty.
-It is not possible to edit images or other attachments, including HTML messages.
-However, they can be deleted for everyone.
-
-Example:
-
-    From: sender@domain
-    To: rcpt@domain
-    Chat-Version: 1.0
-    Message-ID: 00001@domain
-    Content-Type: text/plain

-    Hello wordl!

-The typo from the message above can be fixed by the following message:
