php 使用qmail发送邮件实现代码

function send_check_mail($email, $subject,$uid,$buffer)
{
echo "hello";
$command = "/var/qmail/bin/qmail-inject ".$email; //qmail程序地址,$email是要发送的地址
$handle = popen($command, "w"); //打开管道
if (!$handle) {
return false;
}

$from = "[email protected]"; //发件人
fwrite($handle, "from: ".$from."n"); //往管道写数据
fwrite($handle, "return-path: ".$from."n");
fwrite($handle, "to: ".$uid."n");
fwrite($handle, "subject: ".$subject."n");
fwrite($handle, "mime-version: 1.0n");
fwrite($handle, "content-type: text/html; charset="gb2312"nn");
fwrite($handle, $buffer."n");
pclose($handle); //关闭管道

return true;
}
$subject = "测试邮件";

$uid = $_post['uid']; //from信息
$content= "

".$u_email

." 您好！

谢谢，www.111com.net！
"; //内容信息

$u_email = "[email protected]"; //发送到的邮箱
if (send_check_mail($u_email, $subject, $uid, $content)) {

echo "恭喜！发送投票邮件到您的邮箱！

请检查您的邮箱：".$u_email."

". $close;
} else {

echo "很不幸，发送投票邮件到您的邮箱失败，请重试或者联系开发人员。

". $close;
