我正在尝试使用php（xampp）从我的gmail帐户发送电子邮件。我搜索堆栈溢出，当我得到的东西时，我更改了 xampp 的文件 sendmail.ini 和 php.ini 作为，
在 C：''xampp''php''php 中.ini我删除了行首的分号extension=php_openssl.dll以使 SSL 适用于本地主机的 gmail。
在 php.ini [邮件功能] 下的文件我更改了
SMTP=smtp.gmail.com
smtp_port=25
sendmail_from = mukul.agrawal19@gmail.com
sendmail_path = "'"C:'xampp'sendmail'sendmail.exe'" -t"
然后在 C：''xampp''sendmail''sendmail.ini 中。我用以下代码替换了 sendmail 中的所有现有代码.ini
[sendmail]
smtp_server=smtp.gmail.com
smtp_port=25
error_logfile=error.log
debug_logfile=debug.log
auth_username=mukul.agrawal19@gmail.com
auth_password=my-gmail-password
force_sender=mukul.agrawal19@gmail.com
然后我写了一个简单的邮件函数
<?php
$to = 'mukulagrawal13@live.com';
$subject = 'Test email';
$message = "Hello World!'n'nThis is my first mail.";
$headers = "From: mukul.agrawal19@gmail.com'r'nReply-To: mukul.agrawal19@gmail.com";
$mail_sent = @mail( $to, $subject, $message, $headers );
echo $mail_sent ? "Mail sent" : "Mail failed";
?>
然后通过我的浏览器进入此页面，收到回声，因为邮件失败。
我看到了我的调试文件，我得到了

我不明白问题出在哪里。
好的，我得到了这个工作。不幸的是，不是TLS，因为端口587在我们的网络中被阻止，所以我不得不使用端口465。但我希望TLS也能发挥作用。
我使用了XAMPP 5.6.3。
发送邮件配置：
[sendmail]
smtp_server=smtp.gmail.com
smtp_port=465
smtp_ssl=auto
error_logfile=error.log
debug_logfile=debug.log
auth_username==*****@gmail.com
auth_password=*********
force_sender=*****@gmail.com
PHP配置：
[mail function]
SMTP=smtp.gmail.com
smtp_port=465
sendmail_from = *****@gmail.com
sendmail_path = "'"c:'xampp'sendmail'sendmail.exe'" -t"
法典：
<?php
$to = 'repicient@example.com';
$subject = 'Test email';
$message = "Hello World!'n'nThis is my first mail.";
$headers = "From: *****@gmail.com'r'nReply-To: *****@gmail.com";
$mail_sent = @mail( $to, $subject, $message, $headers );
echo $mail_sent ? "Mail sent" : "Mail failed";
?>
重要：
您需要在GMAIL中启用SMTP访问，还需要允许不安全的客户端：
https://www.google.com/settings/security/lesssecureappshttps://support.google.com/mail/answer/75726
请注意，您要使用的 smtp 端口已在防火墙中打开！我建议尝试使用雷鸟从您的开发机器进行连接检查。然后，您知道客户端是否能够连接。
这是我的结果：
