If `allow_display_name` is set to `true`, the validator will also match Display Name <email-address>. If `require_display_name` is set to `true`, the validator will reject strings without the format Display Name <email-address>. If `allow_utf8_local_part` is set to `false`, the validator will not allow any non-English UTF8 character in email address' local part. If `require_tld` is set to `false`, e-mail addresses without having TLD in their domain will also be matched. If `ignore_max_length` is set to `true`, the validator will not check for the standard max length of an email. If `allow_ip_domain` is set to `true`, the validator will allow IP addresses in the host part. If `domain_specific_validation` is `true`, some additional validation will be enabled, e.g. disallowing certain syntactically valid email addresses that are rejected by GMail. If `blacklisted_chars` receives a `string`, then the validator will reject emails that include any of the characters in the string, in the name part. If `host_blacklist` is set to an array of strings and the part of the email after the @ symbol matches one of the strings defined in it, the validation fails.
