Testing email sending in Django

I need to test that my Django application sends e-mails with correct content. I don't want to rely on external systems (like an ad-hoc gmail account), since I'm not testing the actual e-mail service...

I would like to, maybe, store the emails locally, within a folder as they are sent. Any tip on how to achieve it?

Tying a few of the pieces here together, here's a straightforward setup based on filebased.EmailBackend. This renders a list view linking to the individual log files, which have conveniently timestamped filenames. Clicking a link in the list displays that message in the browser (raw):

Settings

EMAIL_BACKEND = "django.core.mail.backends.filebased.EmailBackend"
EMAIL_FILE_PATH = f"{MEDIA_ROOT}/email_out"

View

import os

from django.conf import settings
from django.shortcuts import render

def mailcheck(request):

    path = f"{settings.MEDIA_ROOT}/email_out"
    mail_list = os.listdir(path)

    return render(request, "mailcheck.html", context={"mail_list": mail_list})

Template

{% if mail_list %}
  <ul>
  {% for msg in mail_list %}
    <li>
      <a href="{{ MEDIA_URL }}email_out/{{msg}}">{{ msg }}</a>
    </li>
  {% endfor %}
  </ul>
{% else %}
  No messages found.
{% endif %}

urls

path("mailcheck/", view=mailcheck, name="mailcheck"),
