const EMAIL_PATTERN = '/^([\w\-\.\+\%]*[\w])@((?:[A-Za-z0-9\-]+\.)+[A-Za-z]{2,})$/';

public static function isEmailValid( $value )

{

    $pattern = self::EMAIL_PATTERN;
    $trimValue = trim($value);

    if ( !preg_match($pattern, $value) )

    {

        return false;

    }
    return true;

}

The problem is that the addresses that contain the string ".@" Are taken for bad, yet are correct, eg "sample.@misite.com"

To register with Oxwall software accepts, but fails to send emails.

See: Cron causes Error 500 but the whole network works perfectly

I understand that it is poorly defined EMAIL_PATTERN

Does anyone know the correct constant to accept these emails?
