Support mail address is broken

[misl6]

Description

The documentation claims:

If you need assistance, you can ask for help on our mailing list:

User Group : https://groups.google.com/group/kivy-users
Email : [email protected]

However, you can't directly email that address (perhaps until you have joined the group). It gives an error by reply email (mentioned in this comment and reproduced by me with a throwaway account.

The documentation should not mention the email address, and stick to the URL.

A PR (which also does a refactor) has been done on buildozer repo:
kivy/buildozer#1722 (comment)

I can resolve this out
