我正在使用 Digital Ocean 来托管一个网站，但我似乎无法让我的 php 邮件功能真正发送邮件。它说它被发送到后缀，但后缀似乎没有将它发送给接收者。
我正在运行此代码：
<?php
$headers = 'From: no-reply@diskise.com' . "\r\n" .
'Reply-To: no-reply@diskise.com' . "\r\n" .
'X-Mailer: PHP/' . phpversion();
$mailed = mail("xxxxxx@gmail.com", "Welcome to Diskise", "Welcome to Diskise!\nI hope you enjoy your stay!", $headers);
if($mailed){
echo "Email was sent!";
}else{
echo "Email was not sent :(";
}
输出显示，我在文件中Email was sent!已更改为：sendmail_pathphp.ini
sendmail_path = /usr/sbin/sendmail -t -i
因此，我得出结论，这与我的后缀配置有关：

我还编辑了这个文件/etc/postfix/virtual，看起来像这样：
no-reply@diskise.com no-reply
所以在一切都配置好后，我重新启动 postfix，然后运行我的 php 文件，我收到了消息Email was sent!，但我从来没有收到电子邮件。
我也这样做：
$ sendmail xxxxxx@gmail.com
Hello.
This is a test!
然后我按CTRL+D发送它，它不会进入我的电子邮件。有什么建议么？
这是尾巴/var/log/mail.log
