+# - Refactor this Dockerfile into a compose.yml
+# - Add another service on the same network running an SMTP server such
+#   as msmtpd or Postfix
+# - Configure the SMTP server to send emails from me@joeac.net via Zoho
+# - Configure the website to use the SMTP server to send emails
+# - Test
+# - Push
+# - Test on RPi
+# - Consider: now you're running an SMTP server anyway, can you send it
+#   from your very own no-reply email address?
