Question

我使用以下代码发送电子邮件。

    $config = Array(
      'protocol' => 'smtp',
      'smtp_host' => 'smtp.sendgrid.net',
      'smtp_user' => 'username',
      'smtp_pass' => 'password',
      'smtp_port' => 587,
      'crlf' => "\r\n",
      'newline' => "\r\n",
      'mailtype' => "html"
    );

    $this->load->library('email', $config);
    $this->email->set_newline("\r\n");
    $this->email->from($email);
    $this->email->to($to);
    $this->email->subject($subject);
    $this->email->message($message);

此代码在我的localhost中正常工作，但每次从cPanel运行此代码时都会收到错误消息。

谁能告诉我应该怎么做？

Answer 1

尝试将最长执行时间设置为更大的数字，并查看它是否适合您。

<?php
    ini_set('max_execution_time', 108000);
?>

OR

你可以改变你的php.ini文件

Answer 2

我不知道你的代码没有用，但当然，这是一个应该每次都能运行的最简单的解决方案，我用它：

$to = "yourTarget@someDomain.com";
$subject = "Your subject";
$message = "<html><body>Your message</body></html>";

$headers = "MIME-Version: 1.0" ."\r\n"
    ."From: theMailYouWantToUse@domain.com" ."\r\n"
    ."Content-type:text/html;charset=UTF-8" ."\r\n"
    ."Reply: reply@yourDomain.com" ."\r\n"
    ."X-Mailer: PHP/" .phpversion();

$mail_success = mail($to,$subject,$message,$headers);

注意：你需要所有这些标题，否则邮件就会发送到垃圾邮件。

我认为最好有一个包含邮件的文件，而且您经常需要修改一些内容。只需在发送之前使用以下代码：

$message = file_get_contents("file.html");
$message = str_replace("%param1%",$param1,$message);
$message = str_replace("%param2%",$param2,$message);

Answer 3

第一个错误Message: fsockopen() [function.fsockopen]: unable to connect to smtp.sendgrid.net:587 (Connection timed out)说了很多关于你的问题。这意味着您无法访问端口587。它可能由以下几个原因发生：

您的服务器上已阻止此端口。
服务器的IP在smtp.sendgrid.net上被阻止（可能是您的服务器在黑名单中）
服务器上的网络问题

据我所知，584端口在smtp.sendgrid.net以及25端口上为我打开。尝试25端口，看看你是否有同样的问题。如果您仍然看到此错误，请让您的托管公司或系统管理员检查服务器防火墙是否为587端口。您还可以尝试telnet <DOMAIN_NAME> <PORT_NUMBER>查看是否可以从服务器连接到特定端口，这可能有助于找到解决此错误的原因。

我正在尝试使用codeigniter从cPanel发送电子邮件，但每次我收到错误说连接超时
