> EmailValidator does not support escaped quotes '\"' within a quoted string as

> 3.2.4|https://tools.ietf.org/html/rfc5322#page-13] as well as in the older
> [RFC2822 section 3.2.5|https://tools.ietf.org/html/rfc2822#page-13].
> These sections indicate that a quoted string can contain a quoted pair
> (escaped characters), where a quoted pair is defined as (in RFC5322):
> {quote}
> quoted-pair = ("\" (VCHAR / WSP)) / obs-qp
> VCHAR = %x21-7E; visible (printing) characters
> {quote}
> The " character is %x22 which falls under the definition of VCHAR above.
> Examples:
> {quote}
> "example\"email"@example.org
> {quote}
