Email address for notifications
        If this field is not empty, an email message will be sent to this address whenever a post written by you is liked, boosted or replied to.

smtp_url    Since version 2.76, email notifications can be sent via direct connection to an SMTP server instead of the traditional behaviour of piping the mes‐
            sage to /usr/sbin/sendmail.  Set this value to the SMTP url to be used for sending email notifications (for example, smtp://localhost). It may  in‐
            clude a port number if it's not running on the usual one, like in smtp://mail.example.com:587.

smtp_user

smtp_password
            To be filled if the SMTP server defined by the previous directive needs credentials.

Telegram notifications
        To  enable  notifications  via Telegram, fill the two provided fields (Bot API key and Chat id). You need to create both a Telegram channel and a
        bot for this; the process is rather cumbersome but it's documented everywhere. The Bot API key is a long string of  alphanumeric  characters  and
        the chat id is a big, negative number.

ntfy notifications
        To  enable  notifications  via  ntfy  (both self-hosted or standard ntfy.sh server), fill the two provided fields (ntfy server/topic and, if pro‐
        tected, the token).  You need to refer to the https://ntfy.sh web site for more information on this process.

Notify webhook
        If this is set to an URL, an HTTP POST will be sent to it whenever a new notification happens (see the 'Webhook for notifications' section  below
        for more information).
