    We have detected that your mailbox <b>{{ mailbox.email }}</b> cannot receive emails as it's a SimpleLogin alias.

  {% call text() %}
    A mailbox needs to be a "final" email address and cannot be an email alias.
  {% endcall %}

  {% call text() %}
    Please update this mailbox to a non-alias email address on
    <a href="{{ mailbox_url }}">{{ mailbox.email }} setting</a>.

    Feel free reply to this email if you have any question. <br>
