Added class to handle various Email connection settings.

Office365 required me setting the Port to another value and also
enabling SSL.

Added a new class 'EmailConnectionInfo' that contains properties used by
the sink instead of direct parameters.
Original extension method still works and now just constructs a
connection info and passes that through.
Spelling mistake

Yay! Spelling!
