HTTP API

WARNING: This is the old API documentation, the new one is located here.

Wild Duck Mail Server is a scalable IMAP / POP3 server that natively exposes internal data through an HTTP API.

This API is not meant to be used by end users but your application.

API Usage Info

Authentication

This API should be used by your application and not by the end users directly, so normally it should probably be hidden behind a firewall.

To add another layer of protection the API can be set to require an access token. The token value can be set in configuration file "api.accessToken". If the value is set, then all requests against the API must include a query argument accessToken with the same value as in the configuration file.

curl "http://localhost:8080/users?query=testuser01&accessToken=secrettoken"

Responses

All successful responses look like the following:

{
  "success": true,
  other response specific fields
}

All failed responses look like the following:

{
    "error": "Some error message"
}

Paging

For paging lists longer than allowed limit, Wild Duck API returns cursors for next and previous pages.

{
    "success": true,
    "total": 200,
    "page": 2,
    "results": ["a list of results"],
    "previousCursor": "abcdef12344",
    "nextCursor": "abcdef12377"
}

The page property in return value is a "soft" argument, you need to set it yourself with the query argument. WildDuck does not know from which page the request was made to but your application does. limit argument limits the output size (in most cases can not be set higher than 250).

Fetch next page using cursors:

GET /users/{user}/mailboxes/{mailbox}/messages?next={nextCursor}&page={page+1}&limit=20

Fetch previous page using cursors:

GET /users/{user}/mailboxes/{mailbox}/messages?previous={previousCursor}&page={page-1}&limit=20

Users

Add a new user

POST /users

Creates a new user, returns the ID upon success.

Parameters

  • username (required) is the username of the user. This is not an email address but authentication username, use only letters and numbers

2FA

Wild Duck supports TOTP and U2f based 2FA. If 2FA is enabled then users are requested to enter authentication token after successful login. Also, with 2FA enabled, master password can not be used in IMAP, POP3 or SMTP. The user must create an Application Specific Password with a correct scope for email clients using these protocols.

2FA checks do not happen magically, your application must be 2FA aware:

  1. Authenticate user with the /authenticate call
  2. If authentication result includes requirePasswordChange:true then force user to change their password
  3. If authentication result includes require2fa:false then do nothing, the user is now authenticated. Otherwise continue with Step 4. or Step 5.
  4. If require2fa array includes 'totp' then:
  5. Request TOTP token from the user before allowing to perform other actions
  6. Check the token with /user/{user}/2fa/totp/check
  7. If token verification succeeds then user is authenticated
  8. If require2fa array includes 'u2f' then:
  9. Authentication response should include u2fAuthRequest object. If it is missing or verification times out then you can fetch a new U2F request object from the server with /user/{user}/2fa/u2f/start
  10. Send authentication request to U2F key
  11. Send authentication response from key to server with /user/{user}/2fa/totp/check
  12. If token verification succeeds then user is authenticated

Setup 2FA

POST /users/{user}/2fa/totp/setup

This call prepares the user to support 2FA tokens. If 2FA is already enabled then this call fails.

Parameters

  • user (required) is the ID of the user
  • issuer is the name to be shown in the Authenticator App
  • fresh is a boolean. If true then generates a new seed even if an old one already exists
  • sess an optional string of user session to be stored in security log
  • ip is the IP address the request was made from

Response fields

  • success should be true
  • qrcode is the data url for the 2FA QR-code. The user must scan the code and return the token with a PUT call

Example

curl -XPOST "http://localhost:8080/users/5971da1754cfdc7f0983b2ec/2fa/totp/setup" -H 'content-type: application/json' -d '{
  "issuer": "testikas",

}

Verify 2FA

POST /users/{user}/2fa/totp/enable

}'

Response for a successful operation:

{
    "success": true,
    "id": "59762d2f9c035be17bbb1fde",
    "password": "mjxlzydlusadfynn"
}

Or with the profile file:

curl -XPOST "http://localhost:8080/users/5971da1754cfdc7f0983b2ec/asps" -H 'content-type: application/json' -d '{
    "description": "Mac OSX Mail Client",

Resulting password should be shown to the client. This password is shown only once so if the user forgets it then the APS should be deleted and replaced with a new one. Application Specific Password can include spaces, so using "slrf waav yzma tgxf" is the same as "slrfwaavyzmatgxf".

Profile file should be sent to the client with Content-Type value of application/x-apple-aspen-config.

res.set('Content-Description', 'Mail App Configuration Profile');
res.set('Content-Type', 'application/x-apple-aspen-config');
res.set('Content-Disposition', 'attachment; filename="profile.mobileconfig"');

  • action_flag is a boolean that marks message as flagged (true) or not (false)
  • action_delete is a boolean that makes the message to be deleted immediately (true). This action does not initiate a bounce, the message is dropeed silently
  • action_spam is a boolean that marks message as spam (true) or not spam (false). Spam messages are automatically moved to the Junk mailbox
  • action_mailbox is the mailbox ID the message should me moved to
  • action_forward is an email address the message should be forwarded to. You can also mix this action with delete.
  • action_targetUrl is a web URL the message should be uploaded to

If a key is not included or is empty in update payload then the key is not used for when filtering.

Example

This example sets up a filter to search for "abc" in From: header, matching messages are flagged.

curl -XPOST "http://localhost:8080/users/59467f27535f8f0f067ba8e6/filters" -H 'content-type: application/json' -d '{
  "query_from": "abc",
  "action_flag": true
}'

Response for a successful operation:

{
    "success": true
}

List existing filters

GET /user/{user}/filters

Lists existing messages in a mailbox

Parameters

  • user (required) is the ID of the user

The listing entries include query and action arrays. These are meant to be human readable descriptions divided into tuples. This would allow using translation on the left side elements (keys). In the end these values should be joined together into a description string.

Example

curl "http://localhost:8080/users/59467f27535f8f0f067ba8e6/filters"

Response for a successful operation:

{
    "success": true,
    "results": [
        {
            "id": "59759c440e1d676f15e76b5f",
            "name": "Flag messages from abc",
            "query": [["from", "(abc)"]],
            "action": [["flag it"]],
            "created": "2017-07-24T07:05:40.355Z"
        }
    ]
}

Archive

Deleted messages are moved to temporary archive from where these are purged after configured delay (defaults to 2 weeks). During that window it is possible to list and restore archived messages. Restoring an archived message resets the UID of a message. Archived messages do not count against user quota.

Updates

Get user related events as an Event Source stream

Stream update events

GET /users/{user}/updates

Parameters

  • user (required) is the ID of the user

Example

Response stream:

data: {"command":"EXISTS", "message":"596e0703f0bdd512aeac3600", "mailbox":"596c9c37ef2213165daadc65",...}
id: 596e0703f0bdd512aeac3605

data: {"command":"CREATE","mailbox":"596e09853f845a14f3620b5c","name":"My Mail",...}
id: 596e09853f845a14f3620b5d

First entry in the event stream indicates that a message with id 596e0703f0bdd512aeac3600 was added to mailbox 596c9c37ef2213165daadc65, second entry indicates that a new mailbox called "My Mail" with id 596e09853f845a14f3620b5c was created.

Be aware though that this connection needs to be properly closed if you do not want to end up with memory leaks.

You can see a demo of catching user events when navigating to http://localhost:8080/public/ (assuming localhost:8080 is your API host).
