Zope.sendmail

==================

- Remove no longer required testing dependency on zope.testing.

- Maildir storage for queue can now handle unicode passed in for message or
to/from addresses (change backported from repoze.sendmail).

- Tests use stdlib doctest instead of zope.testing.doctest.

==================

- Backward compatibility import of zope.sendmail.queue.QueueProcessorThread in
zope.sendmail.delivery.

==================

- Remove dependency on ``zope.security``: the security support is optional,
and only available if the ``zope.security`` package is available. This change
is similar to the optional security support introduced in ``zope.component``
3.8.0, and in fact it uses the same helpers.

- Sort by modification time the messages in zope.sendmail.maildir so earlier
messages are sent before later messages during queue processing.

- Add the new parameter ``processorThread`` to the queuedDelivery ZCML
directive: if False, the QueueProcessorThread is not started and thus an
independent process must process the queue; it defaults to True for b/c.

- Provide a console script ``zope-sendmail`` which can be used to process the
delivery queue in case processorThread is False. The console script can
either process the messages in the queue once, or run in "daemon" mode.

==================

- Depend on ``zope.component`` >= 3.8.0, which supports the new semantic of
zope.component.zcml.proxify needed by zope.sendmail.zcml.

==================

- Use simple vocabulary factory function instead of custom `UtilityTerm`
and `UtilityVocabulary` classes, copied from ``zope.app.component`` in
the previous release.

- Depend on the ``transaction`` package instead of ``ZODB3``.

- Remove zcml slugs and zpkg-related files.

- Work around problem when used with Python >=2.5.1. See
https://bugs.edge.launchpad.net/zope.sendmail/+bug/413335 .

==================

- Copyover the UtilityTerm and UtilityVocabulary implementation from
zope.app.component to avoid a dependency.

- Work around a problem when smtp quit fails, the mail was considered not
delivered where just the quit failed.
