    An attempt to send an email from your alias <b>{{ alias.email }}</b> using <b>{{ sender }}</b> is blocked.
  </h1>
{% endcall %}

{% call text() %}
As a measure to protect against <b>email spoofing</b>, we have blocked 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 alias's owning mailboxes, that are
{{ mailbox_emails|join(", ") }}
{% endcall %}

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

{{ raw_url(authorize_address_link) }}
