提取dedecms邮件函数做到独立页

dedecms的邮件发送只能用系统MAIL函数或者SMTP. 如果服务器是linux基本可不用配置任何SMTP信息。但是如果是windows机器，就必须配置SMTP。
我们配置SMTP会出现意外，比如用QQ邮局。织梦58测试发现
QQ邮箱：
1.  企业邮箱明显比QQ普通邮箱好用，不容易进入垃圾箱
2. QQ邮箱必须配置启用SMTP
3. SSL明显比不启用效率高

在DEDECMS关键词函数部分

require_once(dirname(__FILE__).'/../include/common.inc.php'); //在dedecms内必须引用   //邮件发送函数 function sendmail($email, $mailtitle, $mailbody) { global $cfg_sendmail_bysmtp, $cfg_smtp_server, $cfg_smtp_port, $cfg_smtp_usermail, $cfg_smtp_user, $cfg_smtp_password, $cfg_adminemail,$cfg_webname; if($cfg_sendmail_bysmtp == 'Y' && !empty($cfg_smtp_server)) { $mailtype = 'HTML'; require_once(DEDEINC.'/mail.class.php'); $smtp = new smtp($cfg_smtp_server,$cfg_smtp_port,true,$cfg_smtp_usermail,$cfg_smtp_password); $smtp->debug = false; if(!$smtp->smtp_sockopen($cfg_smtp_server)){  ShowMsg('邮件发送失败,请联系管理员','-1');    exit(); } $smtp->sendmail($email,$cfg_webname,$cfg_smtp_usermail, $mailtitle, $mailbody, $mailtype); }else{ @mail($email, $mailtitle, $mailbody, $headers); } }

在相应页面做以下代码

if(!$_POST) exit;         $address = admin@@dede58.com'; $name   = $_POST['name']; $mailto   = $_POST['email']; $mailtitle   = $_POST['subject'];     $mailbody = $_POST['message'];   $sendtime = time();            if(get_magic_quotes_gpc()) { $comment = stripslashes($comment); }     $msg  = "You have been contacted by $name with regards to $mailtitle.rnn"; $msg .= "$mailbodyrnn"; $msg .= "You can contact $name via email, $mailto.rnn"; $msg .= "-------------------------------------------------------------------------------------------rn";     if(@sendmail($address, $mailtitle, $msg, "From: $mailtornReturn-Path: $mailtorn")) { echo "

Thanks for Contact Us.

"; } else { echo "

邮件发送成功

"; } ?>

再去包含个HTML页，就可以让用户通过邮件留言了
