我正在使用Digital Ocean来托管一个网站，我似乎无法让我的php邮件功能实际发送邮件。它说它被发送到postfix，但postfix似乎没有发送到接收器。
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 Email was sent! ，我已将sendmail_path文件中的php.ini更改为：
sendmail_path = /usr/sbin/sendmail -t -i
因此，我得出结论，它必须与我的后缀配置有关：

# line of that file to be used as the name. The Debian default

我还编辑了这个文件/etc/postfix/virtual，如下所示：
no-reply@diskise.com no-reply
所以在配置完所有内容后，我重新启动postfix，然后运行我的php文件，我收到消息 Email was sent! ，但我从未收到该电子邮件。
我也这样做：
$ sendmail xxxxxx@gmail.com
Hello.
This is a test!
然后按CTRL+D发送它，它不会转到我的电子邮箱。有什么建议吗？
这是/var/log/mail.log

答案 0 :(得分：0)
从您的日志文件中可以看到，您的postfix安装有错误，并且发送邮件的整个过程在其初始阶段失败。
如果你想发送任何邮件，你应该解决这个问题。
