+# 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 `mailbox NAME` to enable email address `NAME@matrix.domain` and start receiving emails
+
+Send `help` to the room to see the bot's help menu for additional commands.
+
+You can also refer to the upstream [documentation](https://gitlab.com/etke.cc/postmoogle).
