三种邮件发送介绍：（Smtp，Mail以及phpmailer）ThinkPhp 框架下开发。
邮件发送配置先前准备(用该账号做测试用)：(这里用新浪邮箱服务器)将自己的新浪邮箱开通 POP3/SMTP服务：
新浪邮箱中 ：设置->账户下面的 POP3/SMTP服务 选择开通（然后一步一步完成开通）。
客户端html代码：
1 <body> 2 <!--<h1>发送信息测试</h1>--> 3 <div>请输入发送地址(1)：<input id="adds" type="text" style="180px;" /></div> 4 <div>主题：<input id="title" type="text" style="100px;" /></div> 5 <div style="600px;vertical-align:top;"> 6 发送信息: 7 <textarea id="msgbody" property="请输入需要发送的信息..." style="180px;height:100px;"></textarea> 8 </div> 9 <div> 10 <input type="button" value="发送1" onclick="sendmsg()" /> 11 </div> 12 <body>
js:
1 <script> 2 function sendmsg() { 3 var id = document.getElementById("adds").value; 4 var msg = document.getElementById("msgbody").value; 5 var title = document.getElementById("title").value; 6 var par = /^[a-zA-Z0-9_+.-]+@([a-zA-Z0-9-]+.)+[a-zA-Z0-9]{2,4}$/; 7 8 if (id == "") { 9 alert("输入发送地址"); 10 return; 11 } else if (!par.exec(id)) { 12 alert("填写地址错误！"); 13 return; 14 } 15 showloading(); 16 $.post('__ROOT__/Home/SendEmail/sendMails', { email: id,title:title, msg: msg }, function (data) { 17 if (data.status == 1) { 18 hideloading(); 19 // try { 20 alert("信息发送成功！"); 21 alert(data.data); 22 // } catch (e) { 23 // alert(e.message); 24 // } 25 } else { 26 hideloading(); 27 alert("未知错误！"); 28 } 29 }, 'json'); 30 } 31 </script>
第一种：Smtp（PHP）。
1：在ThinkPHP/LibraryLibrary文件夹下新建一个文件夹 HomeClass，在HomeClass 文件夹下新建一个类 命名为：smtp.class.php。（网上能找到的）

2：提交到的后台控制器 SendEmailController.class.php
1 public function sendmsg(){ 2 $email = I ( 'post.email' ); 3 $msgs = I('post.msg'); 4 $title=I('post.title'); 5 6 import("HomeClass.smtp");//引用发送邮件类 7 8 $smtpserver = "smtp.sina.cn";//SMTP服务器 9 $smtpserverport = 25;//SMTP服务器端口 10 $smtpusermail = "******@sina.cn";//SMTP服务器的用户邮箱 11 $smtpuser = "****";//SMTP服务器的用户帐号 12 $smtppass = "*****";//SMTP服务器的用户密码 13 14 $smtpemailto = $email;//发送给谁 15 $mailsubject = $title;//邮件主题 16 $mailtime = date("Y-m-d H:i:s"); 17 $mailbody = $msgs;//邮件内容 18 19 $utfmailbody = iconv("UTF-8","GB2312",$mailbody);//转换邮件编码 20 $mailtype = "TXT";//邮件格式（HTML/TXT）,TXT为文本邮件 21 22 $smtp = new smtp($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. 23 $smtp->debug = FALSE;//是否显示发送的调试信息 FALSE or TRUE 24 25 $datas = $smtp->sendmail($smtpemailto, $smtpusermail, $mailsubject, $utfmailbody, $mailtype); 26 27 $this->ajaxReturn ( array ( 28 'data' => $datas, 29 'status' => 1 30 ) ); 31 }
其中：$smtpusermail 为你的新浪邮箱账号，$smtpuser 为你新浪邮箱账号（邮箱去掉@sina.com）,$smtppass 为你的邮箱密码。第一种邮件发送搞定，你可以发送邮件去另一个邮箱了！！！
第二种：Mail（ThinkPHP）。
1：配置服务器邮箱：在 Application/conf/config.php 文件中添加邮箱配置：
1 'THINK_EMAIL' => array ( 2 3 'SMTP_HOST' => 'smtp.sina.cn', 4 'SMTP_PORT' => '25', 5 'SMTP_USER' => '******@sina.cn', // SMTP服务器用户名 6 'SMTP_PASS' => '******', // SMTP服务器密码 7 'FROM_EMAIL' => '******@sina.cn', // 发件人EMAIL 8 'FROM_NAME' => '****', // 发件人名称 9 'REPLY_EMAIL' => '', // 回复EMAIL（留空则为发件人EMAIL） 10 11 'REPLY_NAME' => '' 12 ),
SMTP_USER 与 FROM_EMAIL 可为同一 邮箱地址。
2：在 HomeClass 文件夹下 新建一个类：Mail.class.php:(网上能找到)
1 <?php 2 3 namespace HomeClass; 4 5 class Mail { 6 /** 7 * 系统邮件发送函数 8 * 9 * @param string $to 10 * 接收邮件者邮箱 11 * @param string $name 12 * 接收邮件者名称 13 * @param string $subject 14 * 邮件主题 15 * @param string $body 16 * 邮件内容 17 * @param string $attachment 18 * 附件列表 19 * @return boolean 20 */ 21 function sendMail($to, $name, $subject = '', $body = '', $attachment = null) { 22 $config = C ( 'THINK_EMAIL' ); 23 vendor ( 'PHPMailer.class#phpmailer' ); // 从PHPMailer目录导class.phpmailer.php类文件 24 $mail = new PHPMailer (); // PHPMailer对象 25 $mail->CharSet = 'UTF-8'; // 设定邮件编码，默认ISO-8859-1，如果发中文此项必须设置，否则乱码 26 27 //$mail->AddAddress($address);//添加联系人 28 29 $mail->IsSMTP (); // 设定使用SMTP服务 30 $mail->SMTPDebug = 0; // 关闭SMTP调试功能 31 // 1 = errors and messages 32 // 2 = messages only 33 $mail->SMTPAuth = true; // 启用 SMTP 验证功能 34 //$mail->SMTPSecure = 'ssl'; // 使用安全协议 35 $mail->Host = $config ['SMTP_HOST']; // SMTP 服务器 36 $mail->Port = $config ['SMTP_PORT']; // SMTP服务器的端口号 37 $mail->Username = $config ['SMTP_USER']; // SMTP服务器用户名 38 $mail->Password = $config ['SMTP_PASS']; // SMTP服务器密码 39 $mail->SetFrom ( $config ['FROM_EMAIL'], $config ['FROM_NAME'] ); 40 $replyEmail = $config ['REPLY_EMAIL'] ? $config ['REPLY_EMAIL'] : $config ['FROM_EMAIL']; 41 $replyName = $config ['REPLY_NAME'] ? $config ['REPLY_NAME'] : $config ['FROM_NAME']; 42 $mail->AddReplyTo ( $replyEmail, $replyName ); 43 $mail->Subject = $subject; 44 45 $mail->MsgHTML ( $body ); 46 $mail->AddAddress ( $to, '亲' ); 47 if (is_array ( $attachment )) { // 添加附件 48 foreach ( $attachment as $file ) { 49 is_file ( $file ) && $mail->AddAttachment ( $file ); 50 } 51 } 52 return $mail->Send () ? true : $mail->ErrorInfo; 53 } 54 }
3：将前面JS代码的post提交链接改为 __ROOT__/Home/SendEmail/sendMails2，在刚才的控制器 SendEmailController.class.php 中添加一个方法： sendMail2().
1 public function sendMails2(){ 2 $email = I ( 'post.email' ); 3 $msgs = I('post.msg'); 4 $title=I('post.title'); 5 6 $msg = HomeClassMail::sendMail ( $email, $email, $title, $msgs ); 7 8 $this->ajaxReturn ( array ( 9 'data' => $msg, 10 'status' => 1 11 ) ); 12 }
第三种：PHPMailer（ThinkPHP）
1：看看ThinkPHP框架的 Library/Vendor 文件夹下是否存在 文件夹 PHPMailer，如果不存在，则在网上找个加入在该文件夹下。
2：将前面的JS提交链接改为 __ROOT__/Home/SendEmail/sendMails3 ，在控制器里添加方法 sendMail3():
1 public function sendmsg3($sendto_email, $user_name='', $subject, $bodyurl) 2 { 3 4 $email = I ( 'post.email' ); 5 $title=I('post.title'); 6 $msgs = I('post.msg'); 7 8 vendor ( 'PHPMailer.class#phpmailer' ); 9 $mail = new PHPMailer(); 10 $mail->IsSMTP(); // send via SMTP 11 12 $mail->Host = "smtp.sina.cn"; // SMTP 服务器 13 $mail->Port = 25; // SMTP服务器的端口号 14 $mail->SMTPAuth = true; // turn on SMTP authentication 15 $mail->Username = "*****@sina.cn"; // SMTP服务器用户名 16 $mail->Password = "******"; // SMTP服务器密码 17 18 $mail->From = "*******@sina.cn"; // 发件人邮箱 19 //$mail->FromName = "****";; // 发件人 20 21 $mail->CharSet = "utf-8"; // 这里指定字符集！ 22 $mail->Encoding = "base64"; 23 24 if($user_name == '') 25 { 26 $user_name=$sendto_email; 27 } 28 $mail->AddAddress($sendto_email,$sendto_email); // 收件人邮箱和姓名 29 30 //$mail->WordWrap = 50; // set word wrap 换行字数 31 //$mail->AddAttachment("/var/tmp/file.tar.gz"); // attachment 附件 32 //$mail->AddAttachment("/tmp/image.jpg", "new.jpg"); 33 34 $mail->IsHTML(true); // send as HTML 35 // 邮件主题 36 $mail->Subject = $subject; 37 38 //$urls=urlencode($bodyurl); 39 $mail->Body="Hi,欢迎注册！"; 40 $mail->AltBody = "text/html"; 41 42 if (!$mail->Send()) 43 { 44 $mail->ClearAddresses(); 45 return "邮件错误信息: " . $mail->ErrorInfo; 46 exit; 47 } 48 else 49 { 50 $mail->ClearAddresses(); 51 // $this->assign('waitSecond', 6); 52 // $this->success("注册成功,系统已经向您的邮箱：{$sendto_email}发送了一封激活邮件!请您尽快激活~~<br />"); 53 //$this->redirect('sendhtml', array('send' => 5,'email'=>$sendto_email)); 54 return "亲！已经向您的邮箱：{$sendto_email}发送了一封激活邮件!请您尽快激活~~"; 55 } 56 }
现在可以给另一个邮箱发送邮件了！！！
发送邮件页面：
接收到的邮件：
注：以上配置我只在给新浪邮箱发送邮件时成功，给QQ邮箱发送邮件时都已失败而告终，还搞不懂是为啥？？
