前一段时间研究了好一阵子的PHP发邮件程序，PHP自带的mail()函数在许多空间都不起作用，所以我选择了使用邮件提供商的smtp发邮件。网络上这样的文章真不少，可是很多都是不能使用的，不是修改php.ini就是要安装qmail之类的大型软件，这对于我们这些寄人篱下的站长无疑是想入非非，也给我造成了很多误导，曾经发现了一个发送成功的代码，但只能在在新网的空间上实现，而且极其不稳定，不是我想要的，那几天郁闷的我一直在看英文的[RFC 2195]规范……看得我快吐了。但是那个程序再怎么说也通过了，而且有时候还能支持Gmail的服务器，贴出来大家看一下：

另外不知道新网的php.ini的配置是如何的，大家可以通过这个地址查看一下新网空间的<phpinfo();>
http://www.f1boat.cn/test.php上面的程序给大家一个参考研究的例子，我想下面的程序可能是大家最想得到的，这也是我这几天来发现的最稳定的PHP利用Smtp发邮件的最稳定的方法。
我测试使用的是126的服务器，鉴于126与163的亲缘关系，163的服务器肯定也可以使用，本地空间已测试没有问题，连接速度很快，也很稳定，但是不支持Gmail服务器，显示错误“530 5.7.0 Must issue a STARTTLS command first 10sm4727451nzo 54”，可能是对话方式不搭配，但国内服务器能稳定发邮件对我来说就足够了，以下就是代码：
<?php
### 本程式由 "中国频道" 提供，请大家视情况修改
///以下将表单的内容写入message中
while ( list( $key, $val ) = each( $HTTP_POST_VARS ) ) {
$message .= "${key}: ${val}
";
}
if ($message == "") $message = "你好，这是测试邮件！";
if ($to == "") $to = "[email]silbo@126.com[/email]"; //如果表单中没有收件人，请设置默认收件人e-mail
if ($from == "") $from = "[email]silbo@126.com[/email]"; //如果表单中没有寄件人，请设置默认寄件人e-mail
if ($subject == "") $subject = "Hello~~~"; //如果表单中没有指定主题，请设置默认主题
if ($end = send22($to,$from,$subject, $message ) ) echo $end;
else echo "发送成功!";
function send22($to,$from,$subject, $message )
{
//使用本函数之前，务必请定义好以下变量#############################################
$smtp = "smtp.126.com"; //您的SMTP 服务器供应商，可以是域名或IP地址
$check = 1; //SMTP需要要身份验证设值为 1 不需要身份验证值为 0，现在大多数的SMTP服务商都要验证，如不清楚请与你的smtp 服务商联系。
if ($check) {
$username = "silbo"; //您的email帐号名称
$password = "******"; //您的email密码
}
$s_from = "[email]silbo@126.com[/email]"; //此email 必需是发信服务器上的email

//连接服务器
$fp = fsockopen ( $smtp, 25, $errno, $errstr, 60);
if (!$fp ) return "联接服务器失败".__LINE__;
set_socket_blocking($fp, true );
$lastmessage=fgets($fp,512);
if ( substr($lastmessage,0,3) != 220 ) return "错误信息:".$lastmessage.__LINE__;
