Publishing in PECL php extension smtpmail

I am a php developer in china. I have worked six years on it .I love php and love opensource. I want to share something with others. smtpmail is a php extension, it use esmtp protocol to send email . I develop it because of usually php's function mail can't use in china.Use php to write a fsockopen client will cost more time and is hard to a newer learn php. Last , as you know php extension will run faster. A simple example <?php $smtpmail = smtpmail_connect("smtp.qq.com",25,"test","test","utf-8","\n"); smtpmail_from($smtpmail,"from@qq.com","SMTPMAIL"); $result = smtpmail_send($smtpmail,'title','content',"to@qq.com","keminar"); if (!$result) { echo smtpmail_error(); } smtpmail_quit($smtpmail); I choose the PHP License 3.01 for my extension You can get all code from mail attachment or my blog http://blog.linuxphp.org/smtpmail/
