CodeIgniter 电子邮件引发错误

Question

我无法使用 CodeIgniter 发送邮件。它显示以下错误。

fwrite(): send of 28 bytes failed with errno=10054 An existing connection was forcibly closed by the remote host.

这是我在 email.php 库中的设置

public $useragent   = 'CodeIgniter';
public $mailpath    = '/usr/sbin/sendmail'; // Sendmail path
public $protocol    = 'smtp';       // mail/sendmail/smtp
public $smtp_host   = 'smtp.mailhostbox.com';
public $smtp_user   = 'xxx@xx.in';
public $smtp_pass   = 'xxxxxx';
public $smtp_port   = 25;
public $smtp_timeout    = 5;
public $smtp_keepalive  = FALSE;
public $smtp_crypto = '';
public $newline     = "\r\n";

我可以发送电子邮件到昨天。但是从今天早上开始，它会显示此错误。
更新： 我已将主机更改为 gmail ，但仍然无法正常工作。以下是我所做的更改

public $useragent   = 'CodeIgniter';
public $mailpath    = '/usr/sbin/sendmail'; // Sendmail path
public $protocol    = 'smtp';       // mail/sendmail/smtp
public $smtp_host   = 'smtp.gmail.com';
public $smtp_user   = 'noreply.xxx@gmail.com';
public $smtp_pass   = 'xxxxxx';
public $smtp_port   = 465;
public $smtp_timeout    = 5;
public $smtp_keepalive  = FALSE;
public $smtp_crypto = 'ssl';
public $newline     = "\r\n";

但它显示错误为
Message: fsockopen(): unable to connect to ssl://smtp.gmail.com:465:465 (Failed to parse address "smtp.gmail.com:465:465")

我将端口从465改为587如下

public $smtp_port   = 587;
public $smtp_crypto = 'tls';

但我得到了这个错误

Message: stream_socket_enable_crypto(): SSL operation failed with code 1. OpenSSL Error messages: error:14090086:SSL routines:ssl3_get_server_certificate:certificate verify failed

我不明白真正的问题是什么，因为它在所有可能的情况下都会引发错误

你需要初始化配置。see here

举例

function send_email($attributes) {

        $this->load->library('email');

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

        $config['protocol'] = 'smtp';
        $config['smtp_host'] = 'host';
        $config['smtp_port'] = '465';
        $config['smtp_user'] = 'user@smtp.com';
        $config['smtp_from_name'] = 'FROM NAME';
        $config['smtp_pass'] = 'XXX';
        $config['wordwrap'] = TRUE;
        $config['newline'] = "\r\n";
        $config['mailtype'] = 'html';                       

        $this->email->initialize($config);

        $this->email->from($config['smtp_user'], $config['smtp_from_name']);
        $this->email->to($attributes['to']);
        $this->email->cc($attributes['cc']);
        $this->email->bcc($attributes['cc']);
        $this->email->subject($attributes['subject']);

        $this->email->message($attributes['message']);

        if($this->email->send()) {
            return true;        
        } else {
            return false;
        }       

}
