# 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.
|
|
Postmoogle runs an email server through SMTP and allaws you to create mailboxes to the domain you define in the DNS settings.
|
|
|
|
See the project's [documentation](https://gitlab.com/etke.cc/postmoogle) to learn what it does and why it might be useful to you.
|
|
|
|
## Prerequisites
|
|
|
|
### Ports
|
|
|
|
Open the following ports to your server (without it you will not recive email, but you can still send):
|
|
- `25/tcp`: SMTP
|
|
- `587/tcp`: TLS-encrypted SMTP
|
|
|
|
You can change the above default ports through the following variables in the playbook:
|
|
|
|
```yaml
|
|
# on-host ports
|
|
matrix_bot_postmoogle_smtp_host_bind_port: '25'
|
|
matrix_bot_postmoogle_submission_host_bind_port: '587'
|
|
```
|
|
|
|
|
|
### 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
|
|
```
|
|
|
|
Add an admin to Postmoogle with:
|
|
```yaml
|
|
matrix_bot_postmoogle_admins:
|
|
- '@yourAdminAccount:domain.com'
|
|
```
|
|
|
|
### DNS
|
|
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.
|
|
|
|
You can also refer to the upstream [documentation](https://gitlab.com/etke.cc/postmoogle).
|
|
|
|
### Debug/Logs
|
|
In case you need to debug declare:
|
|
|
|
```yaml
|
|
matrix_bot_postmoogle_loglevel: 'DEBUG'
|
|
```
|
|
|
|
And access it through `journalctl -fu matrix-bot-postmoogle` |
