夹缝中求生存

利用php虚拟主机向指定QQ邮箱账户发送一份电子邮件,以163邮箱为例。

前言:在阿里云虚拟主机php的苛刻环境下,php函数库少的可怜,各种不支持,想要发送一份不被收件邮箱屏蔽的邮件,顿时感觉整个世界都黑暗了,不过还好,在夹缝中求生存,踩过了各种坑,最后还是有解决之道的。

  • 首先得注册163个人邮箱账号,配置SMTP并设置授权密码(此部分不再赘述,如有疑问请自行百度)。
  • 几点提醒:
    • 邮件发送成功却未收到邮件提醒:发送的邮件可能被放到了垃圾箱,尤其是注意账户为QQ邮箱的收件人。
    • 邮件内容不要太多,否则很有可能会被当成垃圾邮件处理(亲测发送整段html代码邮件会被QQ收件邮箱会屏蔽拒收邮件,而163收件邮箱会正常接收邮件),尤其是注意账户为QQ邮箱的收件人。
    • 以下是以163邮箱配置smpt,亲测代码可用,其他邮箱配置smpt未作尝试。
    • 已解决自定义发件人,代码中已写明。
    • 已解决当收件邮箱为QQ邮箱时,邮件会被QQ邮箱当作垃圾邮件处理的问题。
  • 以下是php代码:

test.php

 1 <?php
 2 header("Content-Type: text/html; charset=utf-8");
 3 
 4 //引入发送邮件类
 5 require("smtp.php");
 6 //使用163邮箱服务器
 7 $smtpserver = "smtp.163.com";
 8 //163邮箱服务器端口
 9 $smtpserverport = 25;
10 //你的163服务器邮箱账号
11 $smtpusermail = "****@163.com";//
12 //收件人邮箱,***@163.com/***@qq.com
13 $smtpemailto = "707490440@qq.com";
14 //发送人,可随意显示发件人
15 $sender = "邮件发送方";
16 //你的邮箱账号(去掉@163.com)
17 $smtpuser = "****";//你的163邮箱去掉后面的163.com
18 //你的邮箱密码
19 $smtppass = "*****"; //你的163邮箱SMTP的授权码,千万不要填密码!!!
20 
21 //邮件主题
22 $mailsubject = "邮件提醒";
23 //邮件内容
24 $mailbody = "
25 详细信息:</br>
26 <h1>这是一封测试邮件</h1>
27 ";
28 //邮件格式(HTML/TXT),TXT为文本邮件
29 $mailtype = "HTML";
30 //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.
31 $smtp = new smtp($smtpserver,$smtpserverport,true,$smtpuser,$smtppass);
32 //是否显示发送的调试信息
33 $smtp->debug = TRUE;
34 //发送邮件
35 $smtp->sendmail($smtpemailto, $smtpusermail, $sender ,$mailsubject, $mailbody, $mailtype);
