------------------------------------
Summary: EmailValidator does not support escaped quotes in a
quoted string
Key: VALIDATOR-384
URL: https://issues.apache.org/jira/browse/VALIDATOR-384
Project: Commons Validator
Issue Type: Bug
Components: Routines
Affects Versions: 1.4.1 Release
Reporter: Kris Babic
Priority: Minor
EmailValidator does not support escaped quotes '\"' within a quoted string as
specified by [RFC5322 section
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}
