Answer 1

一个非常不错的发邮件的类,(在网上找的),跟大家共享,代码太长,分成三个部份了.
<?php##########服务器参数设置################
$smtpserver = "";//SMTP服务器
$smtpserverport =25;//SMTP服务器端口
$smtpusermail = "";//SMTP服务器的用户邮箱
$smtpuser = "";//SMTP服务器的用户帐号
$smtppass = "";//SMTP服务器的用户密码
$mailtype = "TXT";//邮件格式（HTML/TXT）,TXT为文本邮件
$mailsubject = "just a test";//邮件主题
$mailbody    = "hello"       //邮件内容
##########################################
$smtp = new smtp($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 = TRUE;//是否显示发送的调试信息
$smtp->sendmail($smtpemailto, $smtpusermail, $mailsubject, $mailbody, $mailtype)
