+Working with mails
+^^^^^^^^^^^^^^^^^^
+If you want to test anything regarding emails in your development setup, we recommend
+starting Python's debugging SMTP server in a separate shell and configuring pretix to use it.
+Every email will then be printed to the debugging SMTP server's stdout.
+
+Add this to your ``src/pretix.cfg``::
+
+    [mail]
+    port = 1025
+
+Then execute ``python -m smtpd -n -c DebuggingServer localhost:1025``.
