在Zend Framework 2.4中为Zend\Mail\Message设置默认传输方法

use Zend\Mail\Message;

$message = new Message();

use Zend\Mail\Transport\Smtp;
use Zend\Mail\Transport\SmtpOptions;

$transport = new Smtp();
$options = new SmtpOptions([
    'name' => 'smtp.example.com',
    'host' => 'smtp.example.com',
    'port' => 587,
    'connection_class' => 'login',
    'connection_config' => [
        'username' => 'your_username',
        'password' => 'your_password',
        'ssl' => 'tls',
    ],
]);
$transport->setOptions($options);

$message->setTransport($transport);

use Zend\Mail\Transport\Sendmail;

$transport = new Sendmail();

$message->setTransport($transport);

use Zend\Mail\Transport\File;
use Zend\Mail\Transport\FileOptions;

$transport = new File();
$options = new FileOptions([
    'path' => '/path/to/save/mails',
]);
$transport->setOptions($options);

$message->setTransport($transport);

$message->setFrom('sender@example.com', 'Sender Name');
$message->addTo('recipient@example.com', 'Recipient Name');
$message->setSubject('Hello');
$message->setBody('This is the message body.');

use Zend\Mail\Transport\TransportInterface;

$transport = $message->getTransport();
if ($transport instanceof TransportInterface) {
    $transport->send($message);
}
