A regular (non-admin) user works best. + +### Creating a shared room + +After creating a sender user, you should create one or more Matrix rooms that you share with that user. +It doesn't matter who creates and owns the rooms and who joins later (you or the sender user). + +What matters is that both you and the sender user are part of the same room and that the sender user has enough privileges in the room to be able to send messages there. +Inviting additional people to the room is okay too. + +Take note of each room's room id (different clients show the room id in a different place). +You'll need the room id when doing [Configuration](#configuration) below. + + +### Obtaining an access token for the sender user + +In order for the sender user created above to be able to send messages to the room, we'll need to obtain an access token for it. + +To do this, you can execute a command like this: + +``` +curl \ +--data '{"identifier": {"type": "m.id.user", "user": "email2matrix" }, "password": "MATRIX_PASSWORD_FOR_THE_USER", "type": "m.login.password", "device_id": "Email2Matrix", "initial_device_display_name": "Email2Matrix"}' \ +https://matrix.DOMAIN/_matrix/client/r0/login +``` + +Take note of the `access_token` value. You'll need the access token when doing [Configuration](#configuration) below. + + +## Configuration + +After doing the preparation steps above, adjust your `inventory/host_vars/matrix.DOMAIN/vars.yml` configuration like this: + +```yaml +matrix_email2matrix_enabled: true + +matrix_email2matrix_matrix_mappings: + - MailboxName: "my-mailbox" +

the public `https://matrix.DOMAIN`. +However, that's more likely to break in the future if you switch to another server implementation than Synapse. + +Re-run the playbook
