PHPMailer无法发送邮件 - TLS错误？

我是一位有用的助手，可以将文本翻译成中文。

我有一个关于使用phpmailer发送电子邮件的问题。

发送邮件的代码如下：

$mail_User      = "site@xxxxxxx.com";
$mail_Password  = "My Password";
$mail_address   = "site@xxxxxxx.com";
$mail_Name      = "MyName";
$mail_Server    = "222.222.222.222";
$mail_Port      = 25;

    function SendHTMLMail($to, $cc, $bcc, $subject, $body)
    {
        global $mail_User, $mail_Password, $mail_address, $mail_Name, $mail_Server, $mail_Port;
        $correo = new PHPMailer;
        $correo->SMTPDebug = 3;                               // Enable verbose debug output
        $correo->SetLanguage("es", "/phpmailer/language/");
        $correo->IsSMTP();

        $correo->IsHTML(true);
        $correo->Host = $mail_Server;
        $correo->Port = $mail_Port;
        $correo->SMTPAuth =true;
        //$correo->SMTPSecure = 'tls';                            // Enable TLS encryption, `ssl` also accepted
        $correo->Username = $mail_User;
        $correo->Password = $mail_Password;
        $correo->From      = $mail_address;
        $correo->FromName  = $mail_Name;
        $correo->Subject = $subject;
        $correo->Body    = $body;
        $dest = explode (";", $to);
        for ($n=0; isset($dest[$n]); $n++) $correo->AddAddress($dest[$n]);
        $dest = explode (";", $cc);
        for ($n=0; isset($dest[$n]); $n++) $correo->AddCC($dest[$n]);
        $dest = explode (";", $bcc);
        for ($n=0; isset($dest[$n]); $n++) $correo->AddBCC($dest[$n]);
        if ($correo->Send())
            return "";
        else {
            AddLog("Correo no enviado: $correo->ErrorInfo");
            echo "<br>Correo no enviado: $correo->ErrorInfo<br>";
            return "Correo no enviado: $correo->ErrorInfo";
        }
    }

结果如下：

为什么phpmailer不能发送电子邮件？如果代码行是注释，为什么它要尝试使用TLS？我用虚假的敏感数据替换了服务器名称和IP地址。如果我将端口从25更改为587并取消tls行的注释，则结果几乎相同。谢谢。

新测试，相同的结果。

Synchro建议我阅读文档。我将端口从25更改为587并添加了一行$correo->SMTPAutoTLS = true;

$correo->SMTPAuth =true;
$correo->SMTPAutoTLS = true;
//$correo->SMTPSecure = 'tls';                            // Enable TLS encryption, `ssl` also accepted
$correo->Username = $mail_User;
$correo->Password = $mail_Password;

结果如下：

你需要阅读它指向的文档。文档会告诉你为什么它在使用TLS（机会主义）以及如何处理它。 - Synchro

您在邮件服务器上使用的是哪种类型的身份验证？这可能会引起问题，因为它期望建立一个安全连接... - Asur

我可以使用TLS或无加密方式。如果我注释掉"//$correo->SMTPSecure = 'tls';"这一行，安全性就是无加密。如果我取消注释该行，phpmailer将使用TLS。 - FOP

我在phpmailer中调试代码，发现问题似乎出现在startTLS()函数中的这一行：if (!stream_socket_enable_crypto($this->smtp_conn, true, STREAM_CRYPTO_METHOD_TLS_CLIENT))无论我是否使用TLS，都会返回false。 - FOP

确保您的服务器出站端口已打开 - Taylor Reed

是的，那些端口（25、587）是开放的。如果它们没有开放，那么“连接已打开”就不会被记录。谢谢。 - FOP

嗯，我进行了许多测试，但是没有看到文档中提到Synchro的部分，但是Synchro是正确的。

我添加了下面的代码，现在运行良好！

$correo->SMTPOptions = array(
        'ssl' => array(
        'verify_peer' => false,
        'verify_peer_name' => false,
        'allow_self_signed' => true
    )
);

虽然我不使用SSL，但我必须澄清，我不使用SSL是因为phpmailer验证SSL是否可用或已正确配置。

谢谢！
