==========
 Overview
==========

This manual is primarily concerned with 3 "types" of email:

* emails sent by the underlying system
* emails sent via Python logging mechanism
* emails sent explicitly by a Poser/Rattail app

The first, "emails sent by the underlying system" refers primarily to emails
sent by the ``cron`` daemon.  See :doc:`system` for more about those.

The second, "emails sent via Python logging mechanism" is covered in
:doc:`logging`.

The third, "emails sent explicitly by a Poser/Rattail app" is the primary
motivation behind this section of the manual.  In particular see the sections
about :doc:`config`, :doc:`templates` and :doc:`code`.

Finally, if you're sending email to the public, it may be helpful to detect
bounces and e.g. flag an address as invalid if it triggers a bounce.  See
:doc:`bounces` for more on that.
