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

提交表单

PHP simply implements sending emails and preventing them from being treated as spam

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."";
 
    //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。
