# 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.
## Registering the bot user
By default, the playbook will set up the bot with a username like this: `@postmoogle:DOMAIN` .
(to use a different username, adjust the `matrix_bot_postmoogle_login` variable).
You **need to register the bot user manually** before setting up the bot. You can use the playbook to [register a new user ](registering-users.md ):
```
ansible-playbook -i inventory/hosts setup.yml --extra-vars='username=postmoogle password=PASSWORD_FOR_THE_BOT admin=no' --tags=register-user
```
Choose a strong password for the bot. You can generate a good password with a command like this: `pwgen -s 64 1` .
## Adjusting the playbook configuration
Add the following configuration to your `inventory/host_vars/matrix.DOMAIN/vars.yml` file:
```yaml
matrix_bot_postmoogle_enabled: true
# Adjust this to whatever password you chose when registering the bot user
matrix_bot_postmoogle_password: PASSWORD_FOR_THE_BOT
```
## Installing
After configuring the playbook, run the [installation ](installing.md ) command again:
```
ansible-playbook -i inventory/hosts setup.yml --tags=setup-all,start
```
## Usage
To use the bot, invite the `@postmoogle:DOMAIN` into a room you want to use as a mailbox, after that send `!pm mailbox NAME` to enable email address `NAME@matrix.domain` and start receiving emails
Send `!pm help` to the room to see the bot's help menu for additional commands.
