Swift Mailer : Address in mailbox given [] does not comply with RFC 2822, 3.6.2 - swiftmailer

Question

I have a little problem here, when I try to send an email using swiftmailer, I got an error.
Here's my code:
<?php
session_start();
include("config.php");
$dir = dirname(__FILE__);
$session = $_SESSION[serialize];
// Load the SwiftMailer files
require_once($dir.'/swift/swift_required.php');
$hold = 'TIDAK';
// Kondisi - Kondisi yang ada
if($_GET[phase]=='confirm'){
$to = "test#127.0.0.1";
$kalimat = "Invoice Dengan nomor ".$_GET[nosc]." Telah di confirm, mohon di cek di sistem";
$kalimat2 = "Berikut terlampir data Invoice Customer , mohon di pastikan.";
$title = "CONFIRMATION NOTIFICATION";
}
// Convert string dlu
$mailer = new Swift_Mailer(new Swift_MailTransport()); // Create new instance of SwiftMailer
$message = Swift_Message::newInstance()
->setSubject($title) // Message subject
->setTo(array($to)) // Array of people to send to
->setBcc(array($bcc)) // Bcc:
->setFrom(array($_SESSION[mailadmin] => $_SESSION[namauser].''.store('namasite'))) // From:
->setBody($kalimat, 'text/html'); // Attach that HTML message from earlier
// Send the email, and show user message
if($hold<>'YA'){
if ($mailer->send($message)){
echo json_encode(array('success'=>true));
} else {
echo json_encode(array('success'=>false));
}
}
?>
And then when I try to post the data to this file through jquery I got an error, this error I got from firebug.

So guys, anybody can help me here? I really doesn't know what happening here.

Answer 1

It's better if you use a try/catch around the send instruction:
try {
if ($mailer->send($message)){
...
}
} catch (Exception $e) {
$log_error->write_error($e->getMessage() . ';');
}
Or if you validate the email before sending it:
if(!Swift_Validate::email($email)){ //if email is not valid
//do something, skip them or log them
$log_error->log($email);
}

Answer 2

Please make sure there is no white space before or after the email address given.
