我正在使用 codeigniter

我在实时服务器上执行了代码。 使用 print_debugger() 得到以下错误

无法使用 PHP SMTP 发送电子邮件。您的服务器可能不是 配置为使用此方法发送邮件。

public function sendEnquiry() {
            $this->load->library('email');
            $name = $this->input->post("fname");
            $cemail = $this->input->post("email");
            $pno = $this->input->post("phone");
            $message = $this->input->post("message");
            $config['protocol']    = 'smtp';
            $config['smtp_host']    = 'ssl://mail.gatewaykhobar.com';
            $config['smtp_port']    = '465';
            $config['smtp_timeout'] = '7';
            $config['smtp_user']    = '***********';
            $config['smtp_pass']    = '***********';
            $config['charset']    = 'utf-8';
            $config['newline']    = "\r\n";
            $config['mailtype'] = 'text'; // or html
            $config['validation'] = FALSE;

            $this->email->initialize($config);
            $this->email->from('info@gatewaykhobar.com','Gateway Restaurent Contact');
            $this->email->to($cemail); 
            $this->email->subject('Gateway Restaurent Contact Enquiry');

           $this->email->message($message);  
            $send = $this->email->send();
            if($send) {
                echo json_encode("send");
            } else {
                $error = $this->email->print_debugger(array('headers'));
                echo json_encode($error);
            }

        }

Answer 1

将 smtp_port 从 465 更改为 587。

确保$config['newline'] = "\r\n"; 用双引号而不是单引号。

Answer 2

看起来邮件服务器也是由您自己托管的，请尝试从任何电子邮件客户端发送电子邮件。如果失败 - 您的邮件服务器配置有问题，而不是您粘贴的代码 - 请检查服务器日志。

Answer 3

造成这种情况的一个常见原因是 CodeIgniter 与 SMTP 服务器在换行方面的交互方式。您的 SMTP 服务器可能需要 \r\n 而 CodeIgniter 正在使用 \n。

有一个简单的解决方法：在您的 $this->email->initialize() 之后，添加以下内容：

$this->email->set_newline("\r\n");  

这应该让它为你工作。

Answer 4

$mail_config['smtp_host'] = 'smtp.gmail.com';
$mail_config['smtp_port'] = '587';
$mail_config['smtp_user'] = 'user@example.com';
$mail_config['_smtp_auth'] = TRUE;
$mail_config['smtp_pass'] = 'password';
$mail_config['smtp_crypto'] = 'tls';
$mail_config['protocol'] = 'smtp';
$mail_config['mailtype'] = 'html';
$mail_config['send_multipart'] = FALSE;
$mail_config['charset'] = 'utf-8';
$mail_config['wordwrap'] = TRUE;
$this->email->initialize($mail_config);

$this->email->set_newline("\r\n");

我刚刚添加了最后一行

只需将“邮件”用于“协议”数组项，仅此而已...

$config = array();
        $config['useragent']    = $system_name;
        $config['mailpath']     = "/usr/bin/sendmail"; // or "/usr/sbin/sendmail"
        $config['protocol']     = "mail"; //use 'mail' instead of 'sendmail or smtp'
        $config['smtp_host']    = "your domain name";
        $config['smtp_user']    =  $from;
        $config['smtp_pass']    = "*************";
        $config['smtp_port']    =  465;
        $config['smtp_crypto']  = 'ssl';
        $config['smtp_timeout'] = "";
        $config['mailtype']     = "html";
        $config['charset']      = "utf-8";
        $config['newline']      = "\r\n";
        $config['wordwrap']     = TRUE;
        $config['validate']     = FALSE;

我使用了很多时间在 localhost 中运行我的配置代码，但它总是给我一个错误（无法使用 PHP SMTP 发送电子邮件。您的服务器可能未配置为使用此方法发送邮件。 )

但是当在我的服务器中运行下面的代码时，它对我有用。

application>controller>Sendingemail_Controller.php

public function send_mail() {
    $this->load->library('email');   
    $config = array();
    $config['protocol']     = "smtp"; // you can use 'mail' instead of 'sendmail or smtp'
    $config['smtp_host']    = "ssl://smtp.googlemail.com";// you can use 'smtp.googlemail.com' or 'smtp.gmail.com' instead of 'ssl://smtp.googlemail.com'
    $config['smtp_user']    = "my@gmail.com"; // client email gmail id
    $config['smtp_pass']    = "******"; // client password
    $config['smtp_port']    =  465;
    $config['smtp_crypto']  = 'ssl';
    $config['smtp_timeout'] = "";
    $config['mailtype']     = "html";
    $config['charset']      = "iso-8859-1";
    $config['newline']      = "\r\n";
    $config['wordwrap']     = TRUE;
    $config['validate']     = FALSE;
    $this->load->library('email', $config); // intializing email library, whitch is defiend in system

    $this->email->set_newline("\r\n"); // comuplsory line attechment because codeIgniter interacts with the SMTP server with regards to line break

    $from_email = $this->input->post('f_email'); // sender email, coming from my view page 
    $to_email = $this->input->post('email'); // reciever email, coming from my view page
    //Load email library

    $this->email->from($from_email);
    $this->email->to($to_email);
    $this->email->subject('Send Email Codeigniter'); 
    $this->email->message('The email send using codeigniter library');  // we can use html tag also beacause use $config['mailtype'] = 'HTML'
    //Send mail
    if($this->email->send()){
        $this->session->set_flashdata("email_sent","Congragulation Email Send Successfully.");
        echo "email_sent";
    }
    else{
        echo "email_not_sent";
        echo $this->email->print_debugger();  // If any error come, its run
    }
}

我定义 f_email 和 email 的视图页面来自 post 方法。 应用程序>查看>emailtesting.php

<html>
<head>    
    <title> Send Email Codeigniter </title>
</head>
<body>
<?php
echo $this->session->flashdata('email_sent');
echo form_open('/Sendingemail_Controller/send_mail');
?>
<input type = "email" name = "f_email" placeholder="sender email id (from)"  required />
<input type = "email" name = "email"  placeholder="reciever email id (to)" required />
<input type = "submit" value = "SEND MAIL">
<?php
echo form_close();
?>
</body>

如果再次出现错误，请访问以下官方文档：

对于发现此错误的其他人，已经设置了其他地方提到的设置（甚至是 Codeigniter 4）但仍然出现错误，测试正在发生的事情的一种方法是从服务器控制台并使用 telnet。例如：

telnet smtp.yourprovider.com 587

然后针对不同的提供商进行测试，看看是否可行。如果您的提供者没有，但另一个提供者有，那么问题出在您的提供者身上，您应该联系他们。如果两者都无法连接，那么您应该与您的虚拟主机交谈。
