This module offers several classes to implement SMTP (email) servers.
+.. seealso::
+
+ The `aiosmtpd <http://aiosmtpd.readthedocs.io/>`_ package is a recommended
+ replacement for this module. It is based on :mod:`asyncio` and provides a
+ more straightforward API. :mod:`smtpd` should be considered deprecated.

Several server implementations are present; one is a generic
do-nothing implementation, which can be overridden, while the other two offer
specific mail-sending strategies.
