PHP发送邮件-小升的个人站

这里使用的是阿里云的邮件推送服务；

开通阿里云邮件推送服务，根据步骤新建发信域名和发信地址

新建发信域名：一定专门创建一个单独的二级域名，不要使用网站正在使用中的二级域名否则会导致网站域名再次解析网站不能访问；

发信域名新建完之后按照新建域名的配置

在域名解析中解析，解析完验证通过，在发信地址中新建发信域名，发信域名中有一个SMTP密码，这个密码在之后发送邮件时会使用到；

PHP发送邮件代码：

function send_email($sampleinfo){

require(LIB_PATH.'aliyunemail/email.class.php');//引入类文件

//require(LIB_PATH.'email.class.php');

$mailto=$sampleinfo['email'];//收件邮箱

$mailsubject='请查收样本文件';//邮件标题

$samplename = $sampleinfo['sample_title'];

$sampleurl = $sampleinfo['sample_upload_url'];

//邮件内容

$mailbody=<<<aaa

<p style='height: 50px;padding-left: 20px;'>请查收文件"{$samplename}"</p>

</div>

本邮件由 <a href='http://www.a.com' style='color:#0099cc;'>aaa</a> 系统自动发出，请勿直接回复。

</div>

aaa;

$smtpserver = "smtpdm.aliyun.com";//中继主机，使用的阿里云的所以这里是阿里云

$smtpserverport = 25;//SMTP端口

$smtpusermail = "发信地址";

// 发件人的账号，填写控制台配置的发信地址,比如xxx@xxx.com

$smtpuser = "发信账号";

// 访问SMTP服务时需要提供的密码(在控制台选择发信地址进行设置)

$smtppass = "密码";

$mailsubject = "=?UTF-8?B?" . base64_encode($mailsubject) . "?=";

$mailtype = "HTML";

//可选，设置回信地址

$smtpreplyto = "";

$smtp = new Smtp($smtpserver, $smtpserverport, true, $smtpuser, $smtppass);

$smtp->debug = false;//这里在linux中必须要改成false，否则会报500错误

$cc ="";

$bcc = "";

$additional_headers = "";

//设置发件人名称，名称用户可以自定义填写。

$sender = "xx网";

$res = $smtp->sendmail($mailto,$smtpusermail, $mailsubject, $mailbody, $mailtype, $cc, $bcc, $additional_headers, $sender, $smtpreplyto);

return $res;
