php - : pear mail package 验证失败

Question

<?php

    require_once "Mail.php";

    $from = '<from.gmail.com>';
    $to = '<to.yahoo.com>';
    $subject = 'Hi!';
    $body = "Hi,\n\nHow are you?";

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

    $smtp = Mail::factory('smtp', array(
            'host' => 'ssl://smtp.gmail.com',
            'port' => '465',
            'auth' => true,
            'username' => 'johndoe@gmail.com',
            'password' => 'passwordxxx'
        ));

    $mail = $smtp->send($to, $headers, $body);

    if (PEAR::isError($mail)) {
        echo('<p>' . $mail->getMessage() . '</p>');
    } else {
        echo('<p>Message successfully sent!</p>');
    }

?>

但是，该程序在 $mail = $smtp->send($to, $headers, $body); 处失败:

validation failed: johndoe@gmail.com

我已确认电子邮件和密码正确无误。如果我提供无效密码，错误将更改为

incorrect password

我也尝试过在我的帐户上禁用两步验证，但这没有帮助。请告知为什么我可能会在凭据看起来正确的情况下收到此验证错误？

Answer 1

当您在您或收件人的电子邮件中使用无效字符作为电子邮件别名时，通常会收到“验证失败”。

例如:

my_email@gmail.com <first_name.last_name>
my_email@gmail.com <first_name@last_name>

无效字符是:

. (dots)
@ (at)
" (double quotes)
[ (bracket opened without closing)
] (bracket closed without opening)
( (parenthesis opened without closing)
) (parenthesis closed without opening)
