symfony - Changing smtp settings in SwiftMailer dynamically

Question

I'm using SwiftMailer bundle with Symfony 2. I pass my smtp user/password settings in config.yml file, it works great, but I need to take this settings from database, when I'm sending mail. I can acces this params:

$mailer = $this->getContainer()->get('mailer')->getTransport();

But is it possible to change them on runtime ? I dont see any setter methods. many thanks!

Many thanks, but it's not the solution i was looking, on kernel request I don't know which account I'll use. I needed to change settings inside my send mail loop. I found pretty cool solution:

foreach ($locations as $location) {
    // get settings for account
    $user = $location->getSmtpUser();
    $pass = $location->getSmtpPass();

    // switch to new settings
    $transport = $this->getContainer()->get('mailer')->getTransport();            
    $ext = $transport->getExtensionHandlers();
    $auth_handler = $ext[0];            
    $auth_handler->setUserName($user);
    $auth_handler->setPassword($pass);

    // send message using new settings
    $message = Swift_Message::newInstance()
         ->setSubject( $subject )
         ->setFrom( $from )
         ->setTo( $email )
         ->setBody( $body )
         ->setContentType('text/html');

       $this->getContainer()->get('mailer')->send( $message );    
}
