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 );    
}

您可以创建一个 < code> 内核 。 请求 事件收听器, 输入 < code> swiftmailer. transport. real 并设置 smpt info, 例如 。

namespace NamespaceOfYourListener;

use SymfonyComponentEventDispatcherEventSubscriberInterface;
use SymfonyComponentHttpKernelEventGetResponseEvent;

class YourListener implements EventSubscriberInterface
{

    /**
     * @var Swift_Transport_EsmtpTransport
     */
    private $transport;

    /**
     * @var DoctrineORMEntityManager
     */
    private $em;

    public function __construct($transport, $em)
    {
        $this->transport = $transport;
        $this->em = $em;
    }

    public function onKernelRequest(GetResponseEvent $event)
    {
        //fetch info from db
        $this->transport->setHost("host");
        $this->transport->setPort("port");
        $this->transport->setUserName("username");
        $this->transport->setPassword("pass");
    }

    static public function getSubscribedEvents()
    {
        return array(
            KernelEvents::REQUEST => array( onKernelRequest , 0)
        );
    }

}

服务减速,

your_listener:
    class: FQCNOfYourListener
    tags:
        - { name: kernel.event_listener, event: kernel.request, method: onKernelRequest }
    arguments: [@swiftmailer.transport.real, @doctrine.orm.entity_manager]

我知道这有点老了,但是我想在它帮助别人的情况下得到答案。我们正在使用带有 SMTP 运输工具的文件支架,并且需要根据网站建立定制的 SMTP 服务器连接。

我们的解决方案是修改 Swift mailer, 以允许对每条电文添加一些数据, 并将它连接到 Symfony2 s Enterprises Re快递器中。 这让我们得以从每条电文中提取连接信息, 在冲水时 。

我们把它做了成一个捆包,这样它就可以被其它人利用。您可以读到 这里。

In fact, you should call $transport->stop(); because in other way Swift Mailer will not reconnect and old setting will be used during 1 script execution
