Hi,
i think this issue is due to PhpMailer…
when we try to send a email to a valid address… like abc@domain.brussels we receive error
Error:SMTP Error: The following recipients failed: abc@domain.brussels: No such domain at this location
I have see PhpMailer file class.phpmailler.php
we have a code regex that validate address/domain… but i have no skill for that.
if some one can help to validate regex domain like .brussels.
Thanks
public static function validateAddress($address, $patternselect = null)
{
if (is_null($patternselect)) {
$patternselect = self::$validator;
}
if (is_callable($patternselect)) {
return call_user_func($patternselect, $address);
}
//Reject line breaks in addresses; it's valid RFC5322, but not RFC5321
if (strpos($address, "\n") !== false or strpos($address, "\r") !== false) {
return false;
}
if (!$patternselect or $patternselect == 'auto') {
//Check this constant first so it works when extension_loaded() is disabled by safe mode
//Constant was added in PHP 5.2.4
if (defined('PCRE_VERSION')) {
//This pattern can get stuck in a recursive loop in PCRE <= 8.0.2
if (version_compare(PCRE_VERSION, '8.0.3') >= 0) {
$patternselect = 'pcre8';
} else {

}
} elseif (function_exists('extension_loaded') and extension_loaded('pcre')) {
//Fall back to older PCRE
