Version 4.0.0

Issue Tracker

Added

• New slimta.util functions for limiting outbound connections to IPv4.
• New socket_error_log_level variable for better log level control.

Changed

• Constructors and functions that took a tls dictionary now take a context
  argument that should be an SSLContext object. This allows finer
  control of encryption behavior, as well as the ability to pre-load sensitive
  certificate data before daemonization.
• Client connections will now be opportunistic and try to use TLS if it is
  available, even if a key or cert have not been configured.
• The AUTH SMTP extension will now advertise insecure authentication
  mechanisms without TLS, but trying to use them will fail.
• Moved the slimta.system module to slimta.util.system to de-clutter the
  top-level namespace.

Fixed

• Fixed a possible race condition on enqueue.
• Fixed exception when given empty EHLO/HELO string.
• Fixed the fallback from EHLO to HELO in certain situations.
• The session.auth variable now correctly contains the tuple described
  in the documentation.
