Hi! On behalf of all the developers, I'm very happy to announce the release of aiosmtpd 1.1. aiosmtpd is a re-implementation of the stdlib smtpd.py module on top of the asyncio framework. It is compliant with the relevant RFCs (5321, 2033, etc.) and supports both SMTP (Simple Mail Transport Protocol) and LMTP (Local Mail Transport Protocol) out of the box. It provides for running the server both from Python and the command line, and it is extensible both by subclassing and by implementing your own "event handlers". aiosmtpd is compatible with Python 3.5 and 3.6. Changes in 1.1 include: * Dropped support for Python 3.4. Yay for async/await! * Better support for RFC 5321. This includes a minor backward incompatibility: if your handler implements handle_NOOP(), the method must now accept an argument. * Much better support for HELP, including adding a decorator that allows SMTP subclasses to control what shows up in HELP. * General improvements to the command line, including adding a manpage. * General improvements and enhancements in the Controller class. * Fixes to several issues around STARTTLS. Much thanks goes to all our fine contributors!
