Codeigniter：SMTP邮件不工作 [英] Codeigniter: SMTP mail not working

问题描述

我正在尝试设置联系表单，我很难让它使用CI中的SMTP配置。

为了简化，我使用这个简单的代码进行测试：

  $ config = array（
'protocol'=>'smtp'，
'smtp_host'=>'smtp .1and1.es'，
'smtp_port'=> 25，
'smtp_user'=>'[e-mail]'，
'smtp_pass'=>'*** *****'，
'mailtype'=>'text'，
'charset'=>'utf-8'，
'wordwrap'=> true，
'wrapchars'=> 50 
）; 
 
 $ this-> load-> library（'email'）; 
 $ this-> email-> initialize（$ config）; 
 
 $ this-> email-> from（'[e-mail]'）; 
 $ this-> email-> to（'[e-mail]'）; 
 $ this-> email-> reply_to（'[e-mail]'，'John Doe'）; 
 $ this-> email-> subject（'从网站中的联系表单发送的消息'）; 
 $ this-> email-> message（'Body of message ...'）; 
 
 if（$ this-> email-> send（））{
 return true; 
} 
 echo'<！ - '。 print_r（$ this-> email-> print_debugger（），true）。 ' - >'; 
 return false; 
  

我刚刚问我的托管提供商，所有的SMTP配置是正确的。他们还检查了我的电子邮件帐户是否正常工作。

事实上，如果我选择：

协议=>邮件

邮件传递没有问题。 AFAIK的php mail（）函数也使用托管提供商SMTP，但它只是把它交给服务器并忘记它。

相反，我想使用SMTP身份验证，这会担心电子邮件的分派。但只有通过更改

protocol =>'smtp'

形式有很多处理时间，我终于得到这个调试消息：

这个错误的原因是什么？

解决方案

此人提到有一个配置项有一个单引号的问题：

  $ config ['crlf'] ='\r\\\
'; //应该是\r\\\

 $ config ['newline'] ='\r\\\
'; //应为\r\\\

  

我确定 protocol => mail 不使用您的提供商 - 它将直接从您的服务器发送电子邮件。

如果不是单引号问题，则可能是凭证，防火墙或连接要求不正确的问题（假设您的电子邮件提供商需要TLS / SSL）。

尝试连接到邮件服务器并与另一个客户端发送电子邮件（您可以使用telnet： http://www.wikihow.com/Send-Email-Using-Telnet 或thunderbird或somesuch）来验证协议是否正确。

I'm trying to set up a contact form, and I'm struggling to get it working with the SMTP configuration in CI. However I've successfully tried with the basic 'mail' config.

To cut it short, I'm doing my tests with this simple code:

    $config = array(
        'protocol' => 'smtp',
        'smtp_host' => 'smtp.1and1.es',
        'smtp_port' => 25,
        'smtp_user' => '[e-mail]', 
        'smtp_pass' => '********',
        'mailtype'  => 'text',
        'charset'   => 'utf-8',
        'wordwrap'  => true,
        'wrapchars' => 50            
    );

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

    $this->email->from('[e-mail]');
    $this->email->to('[e-mail]');
    $this->email->reply_to('[e-mail]', 'John Doe');
    $this->email->subject('Message sent from the contact form in website');
    $this->email->message('Body of message...');

    if ($this->email->send()) {
            return true;
    }
    echo '<!--' . print_r($this->email->print_debugger(), true) . '-->'; 
    return false;

I've just asked my hosting provider and all the SMTP config is correct. They've also checked my e-mail account is working properly.

In fact if I choose:

protocol => 'mail'

the message is delivered without problems. AFAIK the php mail() function also uses the hosting provider SMTP but it simply hands it over to the server and forgets it.

Instead I'd like to use SMTP authentication, which worries about the dispatch of the e-mail. But only by changing

protocol => 'smtp'

when I send the form there's a lot of processing time and I finally get this debugging message:

220 smtp.1and1.es (mreu2) Welcome to Nemesis ESMTP server

What might be the reason of this error?

解决方案

This guy mentioned having an issue with a config item having single quotes:

$config['crlf'] = '\r\n';      //should be "\r\n"
$config['newline'] = '\r\n';   //should be "\r\n"

I'm pretty certain protocol => mail does not use your provider -- it will send the email directly from your server.

If it's not the single quote issue, it might be an issue with incorrect credentials, firewall or connection requirement (say if your email provider requires TLS/SSL).

Try connecting to the mail server and send an email with another client (you could use telnet: http://www.wikihow.com/Send-Email-Using-Telnet or thunderbird or somesuch) to verify the protocols are correct.
