php - 如何使用 PEAR Mail 工厂显式禁用 TLS？

Question

使用 PHP，我尝试通过 AuthSMTP(托管 SMTP 服务)路由电子邮件。问题是 PEAR 邮件工厂自动尝试与服务器协商 TLS 连接。 AuthSMTP 不会简单地忽略该尝试，而是会引发错误。我需要一种方法来明确告诉 Mailer 类不要尝试使用 TLS。有什么建议吗？

    $from = "Example <noreply@example.com>";
    $to = $email;
    $subject = "This is an email";

    $body_text = "plain text here";
    $body_html = "<h1>HTML here!</h1>";

    $headers = array ('From' => $from,
    'To' => $to,
    'Subject' => $subject);

    $mime = new Mail_mime('rn');
    $mime->setTXTBody($body_text);
    $mime->setHTMLBody($body_html);

    $body = $mime->get();
    $hdrs = $mime->headers($headers);

    $host = "mail.authsmtp.com";
    $port = 26;
    $username = "my_username";
    $password = "whatever_password";

    $mailer = Mail::factory('smtp',
    array ('host' => $host,
     'auth' => true,
     'port' => $port,
     'username' => $username,
     'password' => $password));

    if (PEAR::isError($res)) {
        throw new Exception($res->getMessage());
    } else {
        return true;
    } 

AuthSMTP 给我以下错误:

SMTP: Invalid response code received from server (code: 428, response: 4.0.0 Your account is using SSL - either disable it in your email client or enable it at http://control.authsmtp.com)

最简单的方法是在 PEAR\NET\SMTP.php 中的函数 auth 定义中将 $tls=true 更改为 $tls=false
