# Setting up Postmoogle (optional)

**Note**: email bridging can also happen via the [email2matrix](configuring-playbook-email2matrix.md) bridge supported by the playbook.

The playbook can install and configure [Postmoogle](https://gitlab.com/etke.cc/postmoogle) for you.

It's a bot/bridge you can use to forward emails to Matrix rooms

See the project's [documentation](https://gitlab.com/etke.cc/postmoogle) to learn what it does and why it might be useful to you.


## Adjusting the playbook configuration

Add the following configuration to your `inventory/host_vars/matrix.DOMAIN/vars.yml` file:

```yaml
matrix_bot_postmoogle_enabled: true

# Uncomment and adjust this part if you'd like to use a username different than the default
# matrix_bot_postmoogle_login: postmoogle

# Generate a strong password here. Consider generating it with `pwgen -s 64 1`
matrix_bot_postmoogle_password: PASSWORD_FOR_THE_BOT
```

You will also need to add several DNS records so that postmoogle can send emails.
See [Configuring DNS](configuring-dns.md).


## Installing

After configuring the playbook, run the [installation](installing.md) command again:

```sh
ansible-playbook -i inventory/hosts setup.yml --tags=setup-all,ensure-matrix-users-created,start
```

**Notes**:

- the `ensure-matrix-users-created` playbook tag makes the playbook automatically create the bot's user account

- if you change the bot password (`matrix_bot_postmoogle_password` in your `vars.yml` file) subsequently, the bot user's credentials on the homeserver won't be updated automatically. If you'd like to change the bot user's password, use a tool like [synapse-admin](configuring-playbook-synapse-admin.md) to change it, and then update `matrix_bot_postmoogle_password` to let the bot know its new password


## Usage

To use the bot, invite the `@postmoogle:DOMAIN` into a room you want to use as a mailbox.

Then send `!pm mailbox NAME` to expose this Matrix room as an inbox with the email address `NAME@matrix.domain`. Emails sent to that email address will be forwarded to the room.

Send `!pm help` to the room to see the bot's help menu for additional commands.
