PHP简单实现发送邮件，防被当成垃圾邮件处理的那种！

摘要：邮件服务器使用的是邮箱的需要去邮箱申请邮箱和设置客户端授权密码。尝试发邮件试试成功不会进入垃圾箱作者网站学习交流微信

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。

登录163邮箱->设置->POP3/SMTP/IMAP->客户端授权密码

设置好要记住！

下面就是代码了

index.html

    
        


PHP发邮件-BY TANKING

    

       

       

       

       
    

mail.php

".$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。
