请问 这个能发送给别人email的功能是怎么实现的http://www.givemeaname.com/email_friend.php需要什么条件 有没有现成的代码
而且我收到的email 里边的发件人 就是我添加到这个页面里的
是怎么实现的呢？
那里能找到这样的代码呢？http://www.givemeaname.com/email_friend.php

如过把$All的内容再加处理，就可以实现发送MIME邮件了

//这个是我做的测试，我用的是smtp.163.com，那你的信箱也必须是163.com的，要不人家不让你发！！
//你用这个类的时候你修改成你自己的信箱就可以了
$smtp = new smtp_mail("smtp.163.com","25","你的163.com的帐号","你的密码");
//如果你需要显示会话信息，请将上面的修改成
//$smtp = new smtp_mail("smtp.163.com","25","你的163.com的帐号","你的密码",true);
$smtp->send("你的163.com的帐号@163.com","目标地址","你好","你好");
