很实用的一个完整email发送程序，很简单，把下列代码复制到一个空白文本页面，如index.php，运行就行了。具体实例：http://zsvalley.uhome.net/email/index.php。
以下是完整的源代码：（有任何问题请email：zsvalley@cmmail.com）
<?
if ($ok=='yes'){
// SetCookie("yname", $yname);
// SetCookie("yemail", $yemail);
if (!eregi("^[_.0-9a-z-] @([0-9a-z][0-9a-z-] .) [a-z]{2,3}$",$yemail)){
echo "请正确填写您的EMAIL地址！ <A HREF='javascript:history.go(-1)'>返回</A>";
}elseif(!eregi("^[_.0-9a-z-] @([0-9a-z][0-9a-z-] .) [a-z]{2,3}$",$femail)){
echo "请正确填写您好友的EMAIL地址！ <A HREF='javascript:history.go(-1)'>返回</A>";
}else{
