I think you are missing port and host information in your code,unless you didnt show your whole code,see example here
public function actionViewTest() {
// Render view and get content
// Notice the last argument being `true` on render()
$content = $this->render('viewTest', array(
'Test' => 'TestText 123',
), true);
// Plain text content
$plainTextContent = "This is my Plain Text Content for those with cheap emailclients ;-)\nThis is my second row of text";
// Get mailer
$SM = Yii::app()->swiftMailer;
// Get config
$mailHost = 'mail.example.com';
$mailPort = 25; // Optional
// New transport
$Transport = $SM->smtpTransport($mailHost, $mailPort);
// Mailer
$Mailer = $SM->mailer($Transport);
// New message
$Message = $SM
->newMessage('My subject')
->setFrom(array('from#example.com' => 'Example Name'))
->setTo(array('recipient#example.com' => 'Recipient Name'))
->addPart($content, 'text/html')
->setBody($plainTextContent);
// Send mail
$result = $Mailer->send($Message);
}
If your host is gmail,put the port to 587 or 465
$mail->Port = 587; or $mail->Port = 465;
here is a question almost similar to your question
