php使用smtp.sina.com郵箱發送郵件

須要寫一個smtp發送類

測試sina郵箱能否使用

<?php
include "smtp.php";

$smtpserver = "smtp.sina.com";//您的smtp服務器的地址
$port = 25; //smtp服務器的端口，通常是 25
$smtpuser = "your-mail@sina.com"; //您登陸smtp服務器的用戶名
$smtppwd = "your-password"; //您登陸smtp服務器的密碼
$mailtype = "HTML"; //郵件的類型，可選值是 TXT 或 HTML ,TXT 表示是純文本的郵件,HTML 表示是 html格式的郵件
$sender = "your-mail@sina.com"; //發件人,通常要與您登陸smtp服務器的用戶名($smtpuser)相同,不然可能會由於smtp服務器的設置致使發送失敗
$smtp  =   new smtp($smtpserver,$port,true,$smtpuser,$smtppwd,$sender);
$smtp->debug = true; //是否開啓調試,只在測試程序時使用，正式使用時請將此行註釋
$to = "bubifengyun@sina.com"; //收件人
$subject = "你好";
$body = "<h1>這是一個用 <font color='red'><b> php socket </b></font> 發郵件的測試。
    支持SMTP認證！</h1>
    ";
$send=$smtp->sendmail($to,$sender,$subject,$body,$mailtype);
if($send==1){
    echo "郵件發送成功";
}else{
    echo "郵件發送失敗<br>";
    echo "緣由：".$this->smtp->logs;
}
?>

使用

php mailtest.php

測試可用。感謝原做者分享。
