Yet IMAP had been designed in another age, which resulted in a chatty patchwork of extensions. IMAP lacks decent synchronization primitives to address real-time challenges modern mobile fleet requires, it consumes a lot of bandwidth, requires a lot of round trips which means high latency.

We are not alone to say this! Big players of the field started their own proprietary protocols to address IMAP flaws, and inter-operable standard was yet to be found...

This, is where JMAP comes to play! JMAP builds on decades of experience, and beautifully addresses these challenges using HTTP and JSON standards. Not only does it make applications easier to develop, we also strongly believes it results in an improved experience for the end user.

We plan on writing a user documentation, helping you navigating around the application, and detailing the few configurations you have to perform.

If what you are looking for is not in the user guide then ask us directly in the issues first, we would be glad to help. But also glad to improve our documentation and maybe tweak slightly our UI (user interface).

Then, we plan on introducing a desktop application.

This versatility is enabled by the use of the Flutter framework.

The web-app needs to include an environment file though (here you can see the dummy env.file at the root of the project), with a SERVER_URL parameter, so it knows to which backend it needs to connect to.

For this to run it locally for example, 2 ways:

Edit the env.file by replacing the default value of SERVER_URL to the one pointing to your JMAP backend server. Then build your docker image:

docker build -t tmail-web:latest .

Then you can just simply run your web-app like this:

docker run -d -ti -p 8080:80 --name web tmail-web:latest

Then go to http://localhost:8080 and you should be able to login against your JMAP backend using the Twake Mail web-app.

You can use our official image linagora/tmail-web or just build the docker image locally without any prior changes:

docker build -t tmail-web:latest .

From then, create at the root of the project an environment file (like env.dev.file) where you put the SERVER_URL you want to connect to. Then, to mount it and override the default one while running the container:

docker run -d -ti -p 8080:80 --mount type=bind,source="$(pwd)"/env.dev.file,target=/usr/share/nginx/html/assets/env.file --name web tmail-web:latest

Then go to http://localhost:8080 and you should be able to login against your JMAP backend using the TMail web-app.

We also include a docker-compose.yaml file so you can get a testing environment up quickly. This use our tmail-backend image for the JMAP server.

Here are the steps to setup:

1. Generate JWT keys for tmail-backend:

openssl genpkey -algorithm rsa -pkeyopt rsa_keygen_bits:4096 -out jwt_privatekey
openssl rsa -in jwt_privatekey -pubout -out jwt_publickey

2. Edit the env.file and set SERVER_URL to http://localhost/ (with the trailing slash)
3. Run docker compose up -d to bring up both the frontend and the backend.
4. Run docker compose exec tmail-backend /root/provisioning/provisioning.sh to provision some demo accounts (you don't have to let it run all the way).
5. The TMail web-app should be available at http://localhost:8080. The credentials for demo accounts are:

User: alice@localhost
Password: aliceSecret

User: bob@localhost
Password: bobSecret

User: empty@localhost
Password: emptrySecret

There are many ways to help us, and amongst them:

• Spread the word: Tell people you like Twake Mail, on social medias, via blog posts etc...
• Give us feedbacks... It's hard to make all good decisions from the first time. It is very likely we can benefit from your experience. Did you encountered annoying bugs? Do you think we can better arrange the layout? Do you think we are missing some features critical to you? Tell us in the issues.
• I can code! I wanna help ;-). Wow thanks! Let's discuss your project together in the issues to get you on track!
