Zope-sendmail

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

- 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.

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

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

- If the SMTP server rejects a message (for example, when the sender or
recipient address is malformed), that email stays in the queue forever
(https://bugs.launchpad.net/zope3/+bug/157104).

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

- Add README.txt
- Can now talk to servers that don't implement EHLO
- Fix bug that caused files with very long names to be created
- Fix for https://bugs.launchpad.net/zope3/+bug/157104: move aside mail that's
causing 5xx server responses.
