-
-# Encryption
-
-Messages SHOULD be encrypted by the
-[Autocrypt](https://autocrypt.org/level1.html) standard;
-`prefer-encrypt=mutual` MAY be set by default.
-
-Meta data (at least the subject and all chat-headers) SHOULD be encrypted
-by the [Memoryhole](https://github.com/autocrypt/memoryhole) standard.
-If Memoryhole is not used,
-the subject of encrypted messages SHOULD be replaced by the string
-`Chat: Encrypted message` where the part after the colon MAY be localized.
-
-
-# Outgoing messages
-
-Messengers MUST add a `Chat-Version: 1.0` header to outgoing messages.
-For filtering and smart appearance of the messages in normal MUAs,
-the `Subject` header SHOULD start with the characters `Chat:`
-and SHOULD be an excerpt of the message.
-Replies to messages MAY follow the typical `Re:`-format.
-
-The body MAY contain text which MUST have the content type `text/plain`
-or `mulipart/alternative` containing `text/plain`.
-
-The text MAY be divided into a user-text-part and a footer-part using the
-line `-- ` (minus, minus, space, lineend).
-
-The user-text-part MUST contain only user generated content.
-User generated content are eg. texts a user has actually typed
-or pasted or forwarded from another user.
-Full quotes, footers or sth. like that MUST NOT go to the user-text-part.
-
-    From: sender@domain
-    To: rcpt@domain
-    Chat-Version: 1.0
-    Content-Type: text/plain
-    Subject: Chat: Hello ...
-
-    Hello world!
-
-
-# Incoming messages
-
-The `Chat-Version` header MAY be used
-to detect if a messages comes from a compatible messenger.
-
-The `Subject` header MUST NOT be used
-to detect compatible messengers, groups or whatever.
-
-Messenger SHOULD show the `Subject`
-if the message comes from a normal MUA together with the email-body.
-The email-body SHOULD be converted
-to plain text, full-quotes and similar regions SHOULD be cut.
-
-Attachments SHOULD be shown where possible.
-If an attachment cannot be shown, a non-distracting warning SHOULD be printed.
-
-
-# Forwarded messages
-
-Forwarded messages are outgoing messages that contain a forwarded-header
-before the user generated content.
-
-The forwarded header MUST contain two lines: 
-The first line contains the text
-`---------- Forwarded message ----------`
-(10 minus, space, text `Forwarded message`, space, 10 minus). 
-The second line starts with `From: ` followed by the original sender
-which SHOULD be anonymized or just a placeholder.
-
-    From: sender@domain
-    To: rcpt@domain
-    Chat-Version: 1.0
-    Content-Type: text/plain
-    Subject: Chat: Forwarded message
-
-    ---------- Forwarded message ----------
-    From: Messenger
-
-    Hello world!
-
-Incoming forwarded messages are detected by the header.
-The messenger SHOULD mark these messages in a way that
-it becomes obvious that the message is not created by the sender.
-Note that most messengers do not show the original sender of forwarded messages
-but MUAs typically expose the sender in the UI.
-
-
-# Groups
-
-Groups are chats with usually more than one recipient,
-each defined by an email-address.
-The sender plus the recipients are the group members.
-
-To allow different groups with the same members,
-groups are identified by a group-id.
-The group-id MUST be created only from the characters
-`0`-`9`, `A`-`Z`, `a`-`z` `_` and `-`
-and MUST have a length of at least 11 characters.
-
-Groups MUST have a group-name.
-The group-name is any non-zero-length UTF-8 string.
-
-Groups MAY have a group-image.
-
-
-## Outgoing groups messages
-
-All group members MUST be added to the `From`/`To` headers.
-The group-id MUST be written to the `Chat-Group-ID` header.
-The group-name MUST be written to `Chat-Group-Name` header
-(the forced presence of this header makes it easier
-to join a group chat on a second device any time).
-
-The `Subject` header of outgoing group messages
-SHOULD start with the characters `Chat:`
-followed by the group-name and a colon followed by an excerpt of the message.
-
-To identify the group-id on replies from normal MUAs,
-the group-id MUST also be added to the message-id of outgoing messages.
-The message-id MUST have the format `Gr.<group-id>.<unique data>`.
-
-    From: member1@domain
-    To: member2@domain, member3@domain
-    Chat-Version: 1.0
-    Chat-Group-ID: 12345uvwxyZ
-    Chat-Group-Name: My Group
-    Message-ID: Gr.12345uvwxyZ.0001@domain
-    Subject: Chat: My Group: Hello group ...
-
-    Hello group - this group contains three members
-
-Messengers adding the member list in the form `Name <email-address>`
-MUST take care only to spread the names authorized by the contacts themselves.
-Otherwise, names as _Daddy_ or _Honey_ may be spread
-(this issue is also true for normal MUAs, however,
-for more contact- and chat-centralized apps
-such situations happen more frequently).
-
-
-## Incoming group messages
-
-The messenger MUST search incoming messages for the group-id
-in the following headers: `Chat-Group-ID`,
-`Message-ID`, `In-Reply-To` and `References` (in this order).
-
-If the messenger finds a valid and existent group-id,
-the message SHOULD be assigned to the given group.
-If the messenger finds a valid but not existent group-id,
-the messenger MAY create a new group.
-If no group-id is found,
-the message MAY be assigned
-to a normal single-user chat with the email-address given in `From`.
-
-
-## Add and remove members
-
-Messenger clients MUST construct the member list
-from the `From`/`To` headers only on the first group message
-or if they see a `Chat-Group-Member-Added`
-or `Chat-Group-Member-Removed` action header.
-Both headers MUST have the email-address
-of the added or removed member as the value.
-Messenger clients MUST NOT construct the member list
-on other group messages
-(this is to avoid accidentally altered To-lists in normal MUAs;
-the user does not expect adding a user to a _message_
-will also add him to the _group_ "forever").
-
-The messenger SHOULD send an explicit mail for each added or removed member.
-The body of the message SHOULD contain
-a localized description about what happened
-and the message SHOULD appear as a message or action from the sender.
-
-    From: member1@domain
-    To: member2@domain, member3@domain, member4@domain
-    Chat-Version: 1.0
-    Chat-Group-ID: 12345uvwxyZ

-    Chat-Group-Member-Added: member4@domain
-    Message-ID: Gr.12345uvwxyZ.0002@domain
-    Subject: Chat: My Group: Hello, ...
-
-    Hello, I've added member4@domain to our group.  Now we have 4 members.
-
-To remove a member:
-
-    From: member1@domain
-    To: member2@domain, member3@domain
-    Chat-Version: 1.0
-    Chat-Group-ID: 12345uvwxyZ
-    Chat-Group-Name: My Group
-    Chat-Group-Member-Removed: member4@domain
-    Message-ID: Gr.12345uvwxyZ.0003@domain
-    Subject: Chat: My Group: Hello, ...
-
-    Hello, I've removed member4@domain from our group.  Now we have 3 members.
-
-
-## Change group name
-
-To change the group-name,
-the messenger MUST send the action header `Chat-Group-Name-Changed`
-with the value set to the old group name to all group members.
-The new group name goes to the header `Chat-Group-Name`.
-
-The messenger SHOULD send an explicit mail for each name change.
-The body of the message SHOULD contain
-a localized description about what happened
-and the message SHOULD appear as a message or action from the sender.
-
-    From: member1@domain
-    To: member2@domain, member3@domain
-    Chat-Version: 1.0
-    Chat-Group-ID: 12345uvwxyZ
-    Chat-Group-Name: Our Group
-    Chat-Group-Name-Changed: My Group
-    Message-ID: Gr.12345uvwxyZ.0004@domain
-    Subject: Chat: Our Group: Hello, ...
-
-    Hello, I've changed the group name from "My Group" to "Our Group".
-
-
-## Set group image
-
-A group MAY have a group-image.
-To change or set the group-image,
-the messenger MUST attach an image file to a message
-and MUST add the header `Chat-Group-Image`
-with the value set to the image name.
-
-To remove the group-image,
-the messenger MUST add the header `Chat-Group-Image: 0`.
-
-The messenger SHOULD send an explicit mail for each group image change.
-The body of the message SHOULD contain
-a localized description about what happened
-and the message SHOULD appear as a message or action from the sender.
-
-
-    From: member1@domain
-    To: member2@domain, member3@domain
-    Chat-Version: 1.0
-    Chat-Group-ID: 12345uvwxyZ
-    Chat-Group-Name: Our Group
-    Chat-Group-Image: image.jpg
-    Message-ID: Gr.12345uvwxyZ.0005@domain
-    Subject: Chat: Our Group: Hello, ...
-    Content-Type: multipart/mixed; boundary="==break=="
-
-    --==break==
-    Content-Type: text/plain

-
-    /9j/4AAQSkZJRgABAQAAAQABAAD/2wBDAAYEBQYFBAYGBQYHBw ...
-    --==break==--
-
-The image format SHOULD be image/jpeg or image/png.
-To save data, it is RECOMMENDED
-to add a `Chat-Group-Image` only on image changes.
-
-
-# Set profile image
-
-A user MAY have a profile-image that MAY be spread to his contacts.
-To change or set the profile-image,
-the messenger MUST attach an image file to a message
-and MUST add the header `Chat-Profile-Image`
-with the value set to the image name.
-
-To remove the profile-image,
-the messenger MUST add the header `Chat-Profile-Image: 0`.
-
-To spread the image,
-the messenger MAY send the profile image
-together with the next mail to a given contact
-(to do this only once,
-the messenger has to keep a `profile_image_update_state` somewhere).
-Alternatively, the messenger MAY send an explicit mail
-for each profile-image change to all contacts using a compatible messenger.
-The messenger SHOULD NOT send an explicit mail to normal MUAs.
-
-    From: sender@domain
-    To: rcpt@domain
-    Chat-Version: 1.0
-    Chat-Profile-Image: photo.jpg
-    Subject: Chat: Hello, ...
-    Content-Type: multipart/mixed; boundary="==break=="

-
-    AKCgkJi3j4l5kjoldfUAKCgkJi3j4lldfHjgWICwgIEBQYFBA ...
-    --==break==--
-
-The image format SHOULD be image/jpeg or image/png.
-Note that `Chat-Profile-Image` may appear together with all other headers,
-eg. there may be a `Chat-Profile-Image` and a `Chat-Group-Image` header
-in the same message.
-To save data, it is RECOMMENDED to add a `Chat-Profile-Image` header
-only on image changes.
-
-
-# Miscellaneous
-
-Messengers SHOULD use the header `Chat-Predecessor`
-instead of `In-Reply-To` as the latter one results
-in infinite threads on typical MUAs.
-
-Messengers SHOULD add a `Chat-Voice-message: 1` header
-if an attached audio file is a voice message.
-
-Messengers MAY add a `Chat-Duration` header
-to specify the duration of attached audio or video files.
-The value MUST be the duration in milliseconds.
-This allows the receiver to show the time without knowing the file format.
-
-    Chat-Predecessor: foo123@domain
-    Chat-Voice-Message: 1
-    Chat-Duration: 10000
-
-Messengers MAY send and receive Message Disposition Notifications
-(MDNs, [RFC 8098](https://tools.ietf.org/html/rfc8098),
-[RFC 3503](https://tools.ietf.org/html/rfc3503))
-using the `Chat-Disposition-Notification-To` header
-instead of the `Disposition-Notification-To`
-(which unfortunately forces many other MUAs
-to send weird mails not following any standard).
-
-
-## Sync messages
-
-If some action is required by a message header,
-the action should only be performed if the _effective date_ is newer
-than the date the last action was performed.
-
-We define the effective date of a message
-as the sending time of the message as indicated by its Date header,
-or the time of first receipt if that date is in the future or unavailable.
