email-validator 1.2.1

on Python PyPI

Changes in version 1.2.0:

• Rejecting domains with NULL MX records (when deliverability checks
  are turned on).
• Rejecting unsafe unicode characters. (Some of these checks you should
  be doing on all of your user inputs already!)
• Rejecting most special-use reserved domain names. A new test_environment
  option is added for using @*.test domains.
• Some fixes in the tests.

Version 1.2.1 had minor updates including removing example.com/net/org from the special-use domains list.
