Swiftmailer 配置：使用 gmail 发送邮件

我可以使用 swiftmailer 从我的电脑发送电子邮件，但邮件未在服务器中发送。

我正在使用 swiftmailer 5.0.1。项目详细信息是，

1. Netbeans 中的一个简单的 php 项目
2. 迅捷邮递员 5.0.1
3. 树枝1.13.1

我的代码是

public function init() {
        $this->username = '[email protected] /cdn-cgi/l/email-protection'; 
        $this->password = 'password';
        $this->host = 'ssl://smtp.gmail.com';
        $this->port = 465;
        $this->from = '[email protected] /cdn-cgi/l/email-protection';
        $this->subject = 'Company - contact';
        $this->body_part_type = 'text/html';
    }

public function send_email($from_name_add, $to_add, $fullname, $email, $mobile, $content) {
            $this->init();
            $transport = Swift_SmtpTransport::newInstance($this->host, $this->port)
                    ->setUsername($this->username)
                    ->setPassword($this->password);

            $mailer = Swift_Mailer::newInstance($transport);

            $message = Swift_Message::newInstance();
            $cid = $message->embed(Swift_Image::fromPath('../public_html/pic/logo.png'));
            $this->body = $this->renderEmailTemplate('email', $fullname, $email, $mobile, $content, $cid);
            $message->setSubject($this->subject)
                    ->setFrom(array('[email protected] /cdn-cgi/l/email-protection' => '' . $from_name_add))
                    ->setTo($to_add)
                    ->setContentType($this->body_part_type)
                    ->setBody($this->body);
            $result = $mailer->send($message);
            return $result;
        }

这段代码在我的电脑上运行良好。但是将此代码/项目上传到服务器后，邮件未发送。错误是，

    <br />
<b>Fatal error</b>:  Uncaught exception 'Swift_TransportException' with message 'Connection could not be established with host ssl://smtp.gmail.com [Connection timed out #110]' in /home/am***/lib/Swift/classes/Swift/Transport/StreamBuffer.php:259

HINT:该服务器上已经有一个正在运行的php symfony项目，该项目可以成功发送邮件。

这是 symfony2 代码，

$message = \Swift_Message::newInstance()
                ->setSubject($sub)->setFrom($from)->setTo($to)->setContentType("text/html")
                ->setBody($this->renderView('FZAm***Bundle:Layout:mail.html.twig', array
                    ('name' => $this->fullname, 'mobile' => $this->mobile, 'email' => $this->email,
                    'content' => $this->content, 'time' => $this->sys_time, 'ip' => $userip,
                    'server_time' => date('Y-m-d H:i:s'))
        ));
try {
            $this->get('mailer')->send($message);
// catch and other follows. 

配置详细信息是，

mail_contact_from: [email protected] /cdn-cgi/l/email-protection
  mail_contact_to:   [email protected] /cdn-cgi/l/email-protection
  mail_contact_sub:   Contact info

我仅传递了此详细信息，所有设置均为默认设置。如果需要任何信息，请询问我，我会发布。

我从 symfony2 项目更改为这个普通的 php+swift+twig 的原因是我的主机只有 100mb，我需要上传更多图像。但symfony2占用的空间更大。

您的实时服务器似乎丢失了OpenSSL，因此您需要启用它才能使安全连接正常工作（即启用php_openssl模块）。另请检查这个问题 https://stackoverflow.com/questions/4846599/sending-email-using-php-gmail-and-swiftmailer-causes-ssl-related-error.
