<?
$to = ""; //修改成您要接收的邮件地址
$subject = "ZDNet Developer article"; 　//邮件主题
$msg = "I completely understand SMTP servers now!"; 　//邮件内容
$headers = "From: sendmail@域名名\r\nReply-To: ";

//headers 中的sendmail@域名是发件人的信箱地址，根据自己的实际情况可以进行修改．

mail("$to", "$subject", "$msg", "$headers");
echo "finished!";
?>

以上是一个用php发邮件的例子，您可以根据您的实际情况进行相应调整．
