### Custom SMTP configuration per site

If you want to configure the SMTP server through which e-mails are sent on a site-by-site basis, this is possible through configuration in the database. Under the `clients` table in the `config` column you can set the following parameters:

```
"smtpTransport": {
    "host": "smtp.gmail.com",
    "port": 465,
    "secure": true,
    "auth": {
        "user": "username@gmail.com",
        "pass": "password"
    }
}
```
