I don't feel any pressure. I just try to stay calm, follow my game plan and try not to overthrown. 
I just graduated and already I'm way behind. 
The best place a person can die, is where they die for others. 
One never ends. It bears all things, believes all things, hopes all things, endures all things. 
Never claim as a right what you can ask as a favor. 
We are never so happy nor so unhappy as we imagine. 
The ''Communism'' of the English intellectual is something explicable enough. It is the patriotism of the deracinated.

楼主的要求当然可以实现，而且大伙早就这样用了，
你不用担心，关于来个 Sample.
建议你下载一个Email的class,我想这种东西到处都有，随便什么地方下载一个都可以用的。
如果在这里贴源代码，正如一楼那样，你看起来肯定晕呼。
Google 搜索一个一下，
或者在 phpe.net 或者 pear.php.net 去找找，这种 Email Class 多得很。Example:include("emailclass.php");
$mail_obj = new Email;
$mail_obj->setFrom($from);        // 发件人
$mail_obj->setTo($to);         // 收件人
$mail_obj->setCC($cc);   // 抄送
$mail_obj->setBCC($bcc);   // 秘密抄送
$mail_obj->setSubject($subject);  // 标题
$mail_obj->setText($txt);         // 文本内容
$mail_obj->setHTML($html);        // HTML内容
$send_result = $mail_obj->send();
if ($send_result) echo "Success";
else echo "Failed";

有没有办法检测 收件人的系统支持HTML邮件还是只文本格式邮件？
