Announcing automx2 release 2021.6

[Ralph Seichter]

Release 2021.6 introduces an "Encryption" element in the Autodiscover
generator to better support server connections which require the use of
STARTTLS. My thanks to GitHub user benschhold for pointing me to a
recently updated version of the Autodiscover documentation.
