php通过smtp发送邮件需要通过一个类smtp

发邮件的代码如下：

require_once 'smtp.php';########################################## $smtpserver = "smtp.sina.com";//SMTP服务器 $smtpserverport = 25;//SMTP服务器端口 $smtpusermail = "god_chen@sina.com";//SMTP服务器的用户邮箱 $smtpemailto = "45323333@qq.com";//发送给谁 $smtpuser = "name";//SMTP服务器的用户帐号 $smtppass = "123456";//SMTP服务器的用户密码 $mailsubject = "中文";//邮件主题 $mailbody = "中文
测试下能淤泥新年感";//邮件内容 $mailtype = "HTML";//邮件格式（HTML/TXT）,TXT为文本邮件 ########################################## $smtp = new smtp($smtpserver,$smtpserverport,true,$smtpuser,$smtppass);//这里面的一个true是表示使用身份验证,否则不使用身份验证. $smtp->debug = FALSE;//是否显示发送的调试信息 $smtp->sendmail($smtpemailto, $smtpusermail, $mailsubject, $mailbody, $mailtype)

smtp类的源码如下：
