我试着创建了一个简单的邮件表单。表单本身在我的index.html页面上，但它提交到一个单独的“感谢您的提交”页面thanks . PHP，其中嵌入了上述PHP代码。
代码完美地提交，但从未发送电子邮件。我该如何解决这个问题?
Debian 10.0.0 ('Buster')的Sendmail安装实际上很简单!
php . ini
[mail function]
sendmail_path=/usr/sbin/sendmail -t -i
; (Other directives are mostly windows)
标准sendmail包安装(允许'send'):
su - # Install as user 'root'
dpkg --list # Is install necessary?
apt-get install sendmail sendmail-cf m4 # Note multiple package selection
sendmailconfig # Respond all 'Y' for new install
其他有用的命令:
which sendmail # /usr/sbin/sendmail
which sendmailconfig # /usr/sbin/sendmailconfig
man sendmail # Documentation
systemctl restart sendmail # As and when required
验证(发送能力)
echo "Subject: sendmail test" | sendmail -v <yourEmail>@gmail.com
以上花费了大约5分钟。然后我浪费了5个小时…别忘了检查你的垃圾邮件文件夹!
如果使用PHP发送邮件遇到问题，可以考虑使用PHPMailer或SwiftMailer等替代方案。
当我需要用PHP发送邮件时，我通常使用SwiftMailer。
基本用法:
require 'mail/swift_required.php';
$message = Swift_Message::newInstance()
// The subject of your email
->setSubject('Jane Doe sends you a message')
// The from address(es)
->setFrom(array('jane.doe@gmail.com' => 'Jane Doe'))
// The to address(es)
->setTo(array('frank.stevens@gmail.com' => 'Frank Stevens'))
// Here, you put the content of your email
->setBody('<h3>New message</h3><p>Here goes the rest of my message</p>', 'text/html');
if (Swift_Mailer::newInstance(Swift_MailTransport::newInstance())->send($message)) {
echo json_encode([
"status" => "OK",
"message" => 'Your message has been sent!'
], JSON_PRETTY_PRINT);
} else {
echo json_encode([
"status" => "error",
"message" => 'Oops! Something went wrong!'
], JSON_PRETTY_PRINT);
}

对于任何发现这一点的人，我不建议使用邮件。有一些答案涉及到这个问题，但没有解释为什么会这样。
PHP's mail function is not only opaque, it fully relies on whatever MTA you use (i.e. Sendmail) to do the work. mail will only tell you if the MTA failed to accept it (i.e. Sendmail was down when you tried to send). It cannot tell you if the mail was successful because it's handed it off. As such (as John Conde's answer details), you now get to fiddle with the logs of the MTA and hope that it tells you enough about the failure to fix it. If you're on a shared host or don't have access to the MTA logs, you're out of luck. Sadly, the default for most vanilla installs for Linux handle it this way.
邮件库(PHPMailer、Zend Framework 2+等)的功能与邮件非常不同。它们直接打开接收邮件服务器的套接字，然后通过该套接字直接发送SMTP邮件命令。换句话说，类充当自己的MTA(注意，您可以告诉库使用邮件来最终发送邮件，但我强烈建议您不要这样做)。
这意味着您可以直接看到来自接收服务器的响应(例如，在PHPMailer中，您可以打开调试输出)。不用再猜测邮件是否发送失败或原因。
如果您正在使用SMTP(即您正在调用isSMTP())，您可以使用SMTPDebug属性获得SMTP对话的详细记录。
通过在脚本中包含如下一行来设置该选项:
$mail->SMTPDebug = 2;
您还可以获得更好的界面。对于邮件，你必须设置所有的标题，附件等。有了库，就有了专门的函数来实现这一点。这也意味着函数正在处理所有棘手的部分(比如头文件)。
