使用Swift Mailer，GMail和PHP发送电子邮件，权限被拒绝错误 [英] Sending email with Swift Mailer, GMail and PHP, Permission Denied Error

问题描述

我下载了使用Gmail发送电子邮件的SwiftMailer 4.1.6。我已经为此写了以下代码。

I downloaded SwiftMailer 4.1.6 for sending email using Gmail. I had written the following code for that purpose.

<?php

require_once 'swiftmailer/lib/swift_required.php';

$transport = Swift_SmtpTransport::newInstance('smtp.gmail.com', 465, "ssl")
        ->setUsername('[e-mail]')
        ->setPassword('***********');

$mailer = Swift_Mailer::newInstance($transport);
$message = Swift_Message::newInstance('Wonderful Subject')
        ->setFrom(array('[e-mail]' => 'Jomit Jose'))
        ->setTo(array('[e-mail]' => 'Jomit Jose'))
        ->setBody('This is the text of the mail send by Swift using SMTP transport.');

$numSent = $mailer->send($message);
printf("Sent %d messages\n", $numSent);

，导致以下错误：

Fatal error: Uncaught exception 'Swift_TransportException' with message 
'Connection could not be established with host smtp.gmail.com 
[Permission denied #13]' in 
/home/jomit/public_html/email_test/swiftmailer/lib/classes/Swift/Transport/StreamBuffer.php:266

可能出了什么问题？

推荐答案

我们有这个问题，原因证明是一个SELinux设置，阻止Apache，因此PHP打开任何出口套接字连接。我们已经禁用了它，但忘了 -P 参数，所以在下次重新启动时被还原。如果您使用CentOS，RHEL或其他一些SELinux分发功能，这可能是导致此问题的原因。

We had this problem and the cause turned out to be a SELinux setting that prevents Apache and therefore PHP from opening any outgoing socket connections. We had disabled it but forgot the -P parameter so it was reverted in the next reboot. If you are using CentOS, RHEL or some other SELinux enabled distribution, this is a likely cause for the problem.

可以使用以下命令禁用连接限制： p>

The connection restriction can be disabled with this command:

setsebool -P httpd_can_network_connect on
