Zope-sendmail

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

- Clean up ``does_esmtp`` in faux SMTP connection classes provided by the
tests.
- If the ``QueueProcessorThread`` is asked to stop while sending messages, do
so after sending the current message; previously if there were many, many
messages to send, the thread could stick around for quite a while.

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

- ``QueueProcessorThread`` now accepts an optional parameter *interval* for
defining how often to process the mail queue (default is 3 seconds)

- Several ``QueueProcessorThreads`` (either in the same process, or multiple
processes) can now deliver messages from a single maildir without duplicates
being sent.

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

- Bugfix: Don't keep open files around for every email message
to be sent on transaction commit. People who try to send many emails
in a single transaction now will not run out of file descriptors.

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

Initial release as a separate project, corresponds to ``zope.sendmail``
from Zope 3.4.0a1.
