1.2:
mprove the documentation on enabling STARTTLS.
Add customizable ident field to SMTP class constructor.
Remove asyncio.coroutine decorator as it was introduced in Python 3.5.
Add Controller docstring, explain dual-stack binding.
Gracefully handle ASCII decoding exceptions.
Fix typo.
Improve Controller ssl_context documentation.
Add timeout feature.
1.1:
Drop support for Python 3.4.
As per RFC 5321, §4.1.4, multiple HELO / EHLO commands in the same session are semantically equivalent to RSET.
As per RFC 5321, $4.1.1.9, NOOP takes an optional argument, which is ignored. API BREAK If you have a handler that implements handle_NOOP(), it previously took zero arguments but now requires a single argument.
The command line options --version / -v has been added to print the package’s current version number.
General improvements in the Controller class.
When aiosmtpd handles a STARTTLS it must arrange for the original transport to be closed when the wrapped transport is closed. This fixes a hidden exception which occurs when an EOF is received on the original tranport after the connection is lost.
Widen the catch of ConnectionResetError and CancelledError to also catch such errors from handler methods.
Added a manpage for the aiosmtpd command line script.
Added much better support for the HELP. There’s a new decorator called @syntax() which you can use in derived classes to decorate smtp_*() methods. These then show up in HELP responses. This also fixes HELP responses for the LMTP subclass.
The Controller class now takes an optional keyword argument ssl_context which is passed directly to the asyncio create_server() call.
This is a server for SMTP and related protocols, similar in utility to
the standard library's smtpd.py module, but rewritten to be based
on asyncio for Python 3.
