 `allow_quoted_local=False`: Set to `True` to allow obscure and potentially problematic email addresses in which the part of the address before the @-sign contains spaces, @-signs, or other surprising characters when the local part is surrounded in quotes (so-called quoted-string local parts). In the object returned by `validate_email`, the normalized local part removes any unnecessary backslash-escaping and even removes the surrounding quotes if the address would be valid without them. You can also set `email_validator.ALLOW_QUOTED_LOCAL` to `True` to turn this on for all calls by default.
 
-`allow_domain_literal=False`: Set to `True` to allow bracketed IPv4 and "IPv6:"-prefixd IPv6 addresses in the domain part of the email address. No deliverability checks are performed for these addresses. In the object returned by `validate_email`, the normalized domain will use the condensed IPv6 format, if applicable. The object's `domain_address` attribute will hold the parsed `ipaddress.IPv4Address` or `ipaddress.IPv6Address` object if applicable. You can also set `email_validator.ALLOW_DOMAIN_LITERAL` to `True` to turn this on for all calls by default.

 `allow_display_name=False`: Set to `True` to allow a display name and bracketed address in the input string, like `My Name <[email protected]>`. It's implemented in the spirit but not the letter of RFC 5322 3.4, so it may be stricter or more relaxed than what you want. The display name, if present, is provided in the returned object's `display_name` field after being unquoted and unescaped. You can also set `email_validator.ALLOW_DISPLAY_NAME` to `True` to turn this on for all calls by default.
