Swift Mailer: Multi recipients option doesn't work - php

Question

Although there are many same questions, none of the solutions worked for me. Mail gets sent only if there is only one recipient otherwise generates error below. Also I'm only sending internal emails, no external.
Any idea?
CODE:
$to = 'one#example.com, two#example.com, three#example.com';
$transport = Swift_SmtpTransport::newInstance('192.168.whatever', 25);
$mailer = Swift_Mailer::newInstance($transport);
$message = Swift_Message::newInstance('Test')
->setFrom(array('myself#example.com'))
->setTo(array($to))
->setBody('html content goes here', 'text/html');
$result = $mailer->send($message);
echo $result;
ERROR:
Fatal error: Uncaught exception 'Swift_RfcComplianceException' with message 'Address in mailbox given [one#example.com, two#example.com, three#example.com] does not comply with RFC 2822, 3.6.2.' in C:\wamp\www\ssl\swift_emailer\lib\classes\Swift\Mime\Headers\MailboxHeader.php:308 Stack trace: #0 C:\wamp\www\ssl\swift_emailer\lib\classes\Swift\Mime\Headers\MailboxHeader.php(238): Swift_Mime_Headers_MailboxHeader->_assertValidAddress('lukas.borecki#l...') #1 C:\wamp\www\ssl\swift_emailer\lib\classes\Swift\Mime\Headers\MailboxHeader.php(96): Swift_Mime_Headers_MailboxHeader->normalizeMailboxes(Array) #2 C:\wamp\www\ssl\swift_emailer\lib\classes\Swift\Mime\Headers\MailboxHeader.php(60): Swift_Mime_Headers_MailboxHeader->setNameAddresses(Array) #3 C:\wamp\www\ssl\swift_emailer\lib\classes\Swift\Mime\SimpleHeaderFactory.php(60): Swift_Mime_Headers_MailboxHeader->setFieldBodyModel(Array) #4 C:\wamp\www\ssl\swift_emailer\lib\classes\Swift\Mime\SimpleHeaderSet.php(75): Swift_Mime_SimpleHead in C:\wamp\www\ssl\swift_emailer\lib\classes\Swift\Mime\Headers\MailboxHeader.php on line 308

Answer 1

Try
$to = array('one#example.com', 'two#example.com', 'three#example.com');
....
->setTo($to)

Answer 2

TRy this example with swiftmailer:
parameters.yml
destinatarios: [email1, email2, email3]
services:
your service name:
class: your namespace
arguments: ["%destinatarios%"]
the class of the service:
protected $destinatarios;
public function __construct($destinatarios)
{
$this->destinatarios = $destinatarios;
}
->setCc($this->destinatarios)
