I'm trying to send an invitation to someone to become a user of a private Wordpress blog, but WP apparently doesn't accept an apostrophe appearing in the name in the email address as valid. For example, it seems it would consider maryo'grady@hotmail.com as an invalid email address, because of the apostrophe in Mary's surname. Has anyone else had this problem, and is there a way around it, by substituting a different character in place of the apostrophe?
Filter is_email and sanitize_email, then apply a better check:
namespace Wpse\Email;
add_filter( 'is_email', __NAMESPACE__ . '\check_mail_address', 10, 2 );
add_filter( 'sanitize_email', __NAMESPACE__ . '\check_mail_address', 10, 2 );
function check_mail_address( $result, $email )
{
return filter_var( $email, FILTER_VALIDATE_EMAIL );
}
The PHP function is still not RFC 5321 compliant, but better than the WordPress check.

A better check would be
return filter_var($email, FILTER_VALIDATE_EMAIL) && preg_match('/@.+\./', $email);Source – user40422 May 21 '15 at 13:40 -
@Bondye I wrote this especially to allow me the use of my local addresses. – fuxia♦ May 21 '15 at 13:41

Ok, sorry for the misunderstanding. Maybe rename the function to check_mail_local ;) – user40422 May 21 '15 at 13:43

nice and short (I thought WordPress would never include a code with the PHP
filter_*functions, so I was surprised to find it in one place, theclass-phpmailer.phpclass ;-) – birgire May 21 '15 at 14:17
