    We have recorded an attempt to send an email from your alias <b>{{ alias.email }}</b> using <b>{{ sender }}</b>.
  {% endcall %}

  {% call text() %}
    Please note that sending from this alias only works from one of these mailboxes: <br>
    {% for mailbox in alias.mailboxes %}
      - {{ mailbox.email }} <br>
    {% endfor %}
  {% endcall %}

  {% call text() %}
    This is to protect against <b>email spoofing</b>, i.e. someone else sending emails from your mailbox. <br>
    If {{ sender }} can indeed send emails from your alias, you can add it to the allow list:
  {% endcall %}

  {{ render_button("Allow " + sender, authorize_address_link) }}

  {% call text() %}
    Thanks, <br/>
    SimpleLogin Team.
  {% endcall %}

  {{ raw_url(authorize_address_link) }}
