在CodeIgniter电子邮件库中使用MSMTP

Question

有没有人在使用msmtp时能够成功地使用标准的CodeIgniter电子邮件库发送电子邮件？

我正在运行Ubuntu，并且我已经成功地安装和配置了MSMTP。我已经能够从命令行发送电子邮件，也可以使用默认的PHP mail()函数。

我的application/config/email.php文件如下所示

$config = array(
    'protocol' => 'sendmail',
    'mailpath' => '/usr/bin/msmtp -C /etc/msmtp/.msmtprc -t',
    'smtp_host' => 'smtp.gmail.com',
    'smtp_user' => 'myemail@gmail.com',
    'smtp_pass' => 'xxxxxxxx',
    'smtp_port' => 587,
    'smtp_timeout' => 30,
    'smtp_crypto' => 'tls',
);

但这不管用。如果有人成功了，知道你是怎么做到的就好了。理想情况下，我希望使用CodeIgniter的电子邮件库，因为它有很多我不想自己编写的好功能。

我可以毫不费力地通过CodeIgniter和msmtp发送电子邮件。在我的例子中，我使用了Sendgrid，因为我在使用Gmail和Yahoo的msmtp时遇到了认证问题。这是我的设置(运行在Ubuntu14.04，php 5.5.9，Code Igniter latest上)：

/home/quickshiftin/.msmtprc 配置- msmtp

account sendgrid
host smtp.sendgrid.net
port 587
auth on
tls on
tls_starttls on
tls_trust_file /etc/ssl/certs/ca-certificates.crt
user SendGridUsername
password SendGridPassword

代码触发器控制器- application/controller/Tools.php

class Tools extends CI_Controller {

    public function message()
    {
        $this->load->library('email');

        $this->email->from('some-dude@gmail.com', 'Nate');
        $this->email->to('another-dude@gmail.com');

        $this->email->subject('Send email through Code Igniter and msmtp');
        $this->email->message('Testing the email class.');

        $this->email->send();
    }
}

电子邮件库配置- application/config/email.php

$config = [
    'protocol' => 'sendmail',
    'mailpath' => '/usr/bin/msmtp -C /home/quickshiftin/.msmtprc --logfile /var/log/msmtp.log -a sendgrid -t',
];

通过CLI发送电子邮件的

php index.php tools message

对您的问题的思考

您的etc服务器或命令行用户是否可以读取

• /etc/msmtp/.msmtprc？上述user?
• popen是否可执行在您的PHP environment
• Use a debugger中可能被禁用，以便通过调用CI_Email::_send_with_sendmail方法来确定它失败的原因
• 如果您为msmtp配置了一个日志文件，如我所拥有的，您可以在尝试通过代码触发器发送后查看那里，以捕获潜在的问题

我的电子邮件配置如下：

<?php defined('BASEPATH') OR exit('No direct script access allowed.');
// Mail engine switcher: 'CodeIgniter' or 'PHPMailer'
$config['useragent']        = 'PHPMailer';
// 'mail', 'sendmail', or 'smtp'
$config['protocol']         = 'smtp';
$config['mailpath']         = '/project-folder/sendmail';
$config['smtp_host']        = 'smtp.gmail.com';
$config['smtp_user']        = 'Your Gmail Email';
$config['smtp_pass']        = 'Your Gmail Pass';
$config['smtp_port']        = 587;
// (in seconds)
$config['smtp_timeout']     = 30;

$config['smtp_crypto']      = 'tls'; 
// PHPMailer's SMTP debug info level: 0 = off, 1 = commands, 2 = commands and data, 3 = as 2 plus connection status, 4 = low level data output.                      
$config['smtp_debug']       = 0;

$config['smtp_auto_tls']    = false; 
// SMTP connection options, an array passed to the function stream_context_create() when connecting via SMTP.                   
$config['smtp_conn_options'] = array();                 
$config['wordwrap']         = true;
$config['wrapchars']        = 76;
// 'text' or 'html'
$config['mailtype']         = 'html'; 
// 'UTF-8', 'ISO-8859-15', ...; NULL (preferable) means config_item('charset'), i.e. the character set of the site.                  
$config['charset']          = null;                     
$config['validate']         = true;
// 1, 2, 3, 4, 5; on PHPMailer useragent NULL is a possible option, it means that X-priority header is not set at all
$config['priority']         = 3;
// "\r\n" or "\n" or "\r"
$config['crlf']             = "\n";
// "\r\n" or "\n" or "\r"                     
$config['newline']          = "\n";                     
$config['bcc_batch_mode']   = false;
$config['bcc_batch_size']   = 200;
// The body encoding. For CodeIgniter: '8bit' or '7bit'. For PHPMailer: '8bit', '7bit', 'binary', 'base64', or 'quoted-printable'.
$config['encoding']         = '8bit';
