嘿家伙,我正在尝试使用 codeiginiter 邮件类功能发送电子邮件,但我发现 smtp 协议有问题。我使用 gmail smtp 协议。 我在本地机器上运行它。 我正在使用 Xampp 1.7.4 包,我尝试过如下设置:

function index()


    $config['protocol'] = 'smtp'; // mail, sendmail, or smtp    The mail sending protocol.
    $config['smtp_host'] = 'smtp.gmail.com'; // SMTP Server Address.
    $config['smtp_user'] = 'me@gmail.com'; // SMTP Username.
    $config['smtp_pass'] = '123'; // SMTP Password.
    $config['smtp_port'] = '25'; // SMTP Port.
    $config['smtp_timeout'] = '5'; // SMTP Timeout (in seconds).
    $config['wordwrap'] = TRUE; // TRUE or FALSE (boolean)    Enable word-wrap.
    $config['wrapchars'] = 76; // Character count to wrap at.
    $config['mailtype'] = 'html'; // text or html Type of mail. If you send HTML email you must send it as a complete web page. Make sure you don't have any relative links or relative image paths otherwise they will not work.
    $config['charset'] = 'utf-8'; // Character set (utf-8, iso-8859-1, etc.).
    $config['validate'] = FALSE; // TRUE or FALSE (boolean)    Whether to validate the email address.
    $config['priority'] = 3; // 1, 2, 3, 4, 5    Email Priority. 1 = highest. 5 = lowest. 3 = normal.
    $config['crlf'] = "\r\n"; // "\r\n" or "\n" or "\r" Newline character. (Use "\r\n" to comply with RFC 822).
    $config['newline'] = "\r\n"; // "\r\n" or "\n" or "\r"    Newline character. (Use "\r\n" to comply with RFC 822).
    $config['bcc_batch_mode'] = FALSE; // TRUE or FALSE (boolean)    Enable BCC Batch Mode.
    $config['bcc_batch_size'] = 200; // Number of emails in each BCC batch.

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


    $this->email->from('me@gmail.com', 'Me');
    $this->email->reply_to('me@gmail.com', 'Me');
    $this->email->to('you@yahoo.com');
    $this->email->subject('testing my mail function with CodeIgniter');
    $this->email->message('<html><body>this is the content</body></html>');

    if ( ! $this->email->send())
        echo 'error! <br />';
        // Generate error
    
    echo $this->email->print_debugger();


以下错误显示在我的浏览器中:

【问题讨论】:

【参考方案1】:

出于安全原因,Google 的电子邮件服务器require SSL or TLS 以便发送邮件。它不使用标准的未加密端口 25 方法。

你基本上有两个选择。 1) 使用 sendmail 或您自己服务器上的 mail 来传递消息,或 2) 使用方法 described here 通过 Google 的服务器使用 SSL 发送电子邮件。祝你好运,我希望这会有所帮助。

【讨论】:

如果您选择在 XAMPP 上使用 sendmail,请记住省略 smtp 主机的协议部分,以便您最终得到 smtp_server=smtp.googlemail.com【参考方案2】:

您正尝试在标准 SMTP 端口 25 上通过 Gmail 发送出站邮件。Gmail 不接受该端口(或任何端口)上的未加密连接。您必须通过 SSL 使用端口 465

您必须将您的$config['smtp_port'] 更改为465 并将您的$config['smtp_host'] 更改为'ssl://smtp.googlemail.com'

【讨论】:

你的第二个数组键应该是 smtp_host【参考方案3】:

你甚至可以使用 587 端口:

$config['smtp_port'] = '587';

和 smtp-host 为:

$config['smtp_host'] = 'ssl://smtp.gmail.com';

【讨论】:

只是导致fsockopen(): SSL: An existing connection was forcibly closed by the remote host.【参考方案4】:

我通过在 smtp_host 上添加 ssl 前缀解决了这个问题:

$config['smtp_host'] = 'ssl://smtp.gmail.com';

并且一定要使用 465 端口(即 google 的 smtp 端口):

$config['smtp_port'] = '465';

否则,默认情况下 google 会阻止“低安全性连接”,因此您可以输入您的 google 帐户并配置此选项。

Allow less secure apps to access accounts

激活此选项,然后重试。希望对您有所帮助!

【讨论】:

【参考方案5】:

1) 你的 smtp 端口必须是465

2) 您的 smtp 主机必须是 ssl://smtp.gmail.com

$config['smtp_host'] = 'ssl://smtp.gmail.com'; // SMTP Server Address.

$config['smtp_port'] = '465'; // SMTP Port.
