这篇文章主要介绍了关于PHP简单实现发送邮件和防被当成垃圾邮件处理，有着一定的参考价值，现在分享给大家，有需要的朋友可以参考一下邮件服务器使用的是163邮箱的
需要去163邮箱申请邮箱和设置客户端授权密码。
设置方法
登录163邮箱->设置->POP3/SMTP/IMAP->客户端授权密码
图片演示
设置好要记住！
下面就是代码了
表单
index.html

发送邮件处理
mail.php
<?php//获取表单提交的邮件标题$title = $_POST["title"];//获取表单提交的内容$content = $_POST["content"];include_once("smtp.class.php"); $smtpserver = "smtp.163.com"; //SMTP服务器 $smtpserverport = 25; //SMTP服务器端口 //获取表单提交的邮件接收人邮箱号码 $email = $_POST["email"]; $smtpusermail = "你的163邮箱地址"; //SMTP服务器的用户邮箱 $smtpuser = "你的163邮箱地址"; //SMTP服务器的用户帐号 $smtppass = "授权密码"; //SMTP服务器的授权密码 $smtp = new Smtp($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. $emailtype = "HTML"; //信件类型，文本:text；网页：HTML $smtpemailto = $email; $smtpemailfrom = $smtpusermail; $emailsubject = $title; $emailbody = "<p>".$content."</p>"; //开始发送邮件 $smtp->sendmail($smtpemailto, $smtpemailfrom, $emailsubject, $emailbody, $emailtype); echo "发送成功！";?>mail.php
里面只需设置你的163账号和授权密码即可
还有一个文件
smtp.class.php
这个不要动就行，拷贝到同一目录。
