# Adjusting email-sending settings (optional)
|
|
|
|
By default, this playbook sets up an [Exim](https://www.exim.org/) email server through which all Matrix services send emails.
|
|
|
|
The email server would attempt to deliver emails directly to their final destination. This may or may not work, depending on your domain configuration (SPF settings, etc.)
|
|
|
|
By default, emails are sent from `matrix@matrix.example.com`, as specified by the `exim_relay_sender_address` playbook variable.
|
|
|
|
⚠️ **Warning**: On some cloud providers (Google Cloud, etc.), [port 25 is always blocked](https://cloud.google.com/compute/docs/tutorials/sending-mail/), so sending email directly from your server is not possible. You will need to [relay email through another SMTP server](#relaying-email-through-another-smtp-server).
|
|
|
|
💡 To improve deliverability, we recommend [relaying email through another SMTP server](#relaying-email-through-another-smtp-server) anyway.
|
|
|
|
|
|
## Firewall settings
|
|
|
|
No matter whether you send email directly (the default) or you relay email through another host (see how below), you'll probably need to allow outgoing traffic for TCP ports 25/587 (depending on configuration).
|
|
|
|
|
|
## Relaying email through another SMTP server
|
|
|
|
If you'd like to relay email through another SMTP server, add the following configuration to your `inventory/host_vars/matrix.example.com/vars.yml` file (adapt to your needs):
|
|
|
|
```yaml
|
|
exim_relay_sender_address: "another.sender@example.com"
|
|
exim_relay_relay_use: true
|
|
exim_relay_relay_host_name: "mail.example.com"
|
|
exim_relay_relay_host_port: 587
|
|
exim_relay_relay_auth: true
|
|
exim_relay_relay_auth_username: "another.sender@example.com"
|
|
exim_relay_relay_auth_password: "some-password"
|
|
```
|
|
|
|
**Note**: only the secure submission protocol (using `STARTTLS`, usually on port `587`) is supported. **SMTPS** (encrypted SMTP, usually on port `465`) **is not supported**.
|
|
|
|
|
|
### Configuations for sending emails using Sendgrid
|
|
An easy and free SMTP service to set up is [Sendgrid](https://sendgrid.com/), the free tier allows for up to 100 emails per day to be sent. In the settings below you can provide any email for `exim_relay_sender_address`.
|
|
|
|
The only other thing you need to change is the `exim_relay_relay_auth_password`, which you can generate at https://app.sendgrid.com/settings/api_keys. The API key password looks something like `SG.955oW1mLSfwds7i9Yd6IA5Q.q8GTaB8q9kGDzasegdG6u95fQ-6zkdwrPP8bOeuI`.
|
|
|
|
Note that the `exim_relay_relay_auth_username` is literally the string `apikey`, it's always the same for Sendgrid.
|
|
|
|
```yaml
|
|
exim_relay_sender_address: "arbitrary@email.com"
|
|
exim_relay_relay_use: true
|
|
exim_relay_relay_host_name: "smtp.sendgrid.net"
|
|
exim_relay_relay_host_port: 587
|
|
exim_relay_relay_auth: true
|
|
exim_relay_relay_auth_username: "apikey"
|
|
exim_relay_relay_auth_password: "<your api key password>"
|
|
```
|
|
|
|
## Troubleshooting
|
|
|
|
If you're having trouble with email not being delivered, it may be useful to inspect the mailer logs: `journalctl -f -u matrix-exim-relay`.
