Email address local part can have multiple @ signs as long as the local part is in quotes:

>>> validate_email('"very.(),:;<>[]\".VERY.\"very@\\ \"very\".unusual"@strange.example.com')

This is not supported by design. It's discussed in the README. If you need to accept addresses like that, there are some suggested alternative libraries listed right at the top of the README.
