/**

     * @param array $data 基本参数
     * @return  bool
     */
	function Sendmail($data){
		$config = &get_config();
		$con_mail = $config['mail'];
	    require('phpemailer/class.phpmailer.php');
	    require("phpemailer/class.smtp.php");
	    $mail = new PHPMailer(); //new一个PHPMailer对象出来
	    $body = eregi_replace("[\]",'',$data['body']); //对邮件内容进行必要的过滤
	    $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
	    $mail->IsSMTP(); //设定使用SMTP服务
	    $mail->SMTPDebug  = 1;                     // 启用SMTP调试功能 1 = errors and messages 2 = messages only
	    $mail->SMTPAuth   = true;                  // 启用 SMTP 验证功能
	    $mail->SMTPSecure = "ssl";                 // 安全协议
	    $mail->Host       = $con_mail['smtp_host'];  // SMTP 服务器
	    $mail->Port       = $con_mail['smtp_port'];  // SMTP服务器的端口号
	    $mail->Username   = $con_mail['smtp_user'];  // SMTP服务器用户名
	    $mail->Password   = $con_mail['smtp_pass'];  // SMTP服务器密码
	    $mail->SetFrom($con_mail['admin_mail'], $data['title']);
	    $mail->AddReplyTo($con_mail['admin_mail'],'Hello');
	    $mail->Subject    = $data['title'];
	    $mail->AltBody    = $body;
	    $mail->MsgHTML($data['content']);
	    $mail->AddAddress($data['mail_to'], "Hello Union");
	    if(!$mail->Send()) {
	    	return FALSE;
	        //echo "Mailer Error: " . $mail->ErrorInfo;//错误信息
	    }else{
			unset($mail);
        	return TRUE;
        }
    }

这个是我用在CI里面发邮件的！

$config['mail']['smtp_host'] = 'smtp.gmail.com';
$config['mail']['smtp_user'] = '用户名@gmail.com';
$config['mail']['smtp_pass'] = '密码';
$config['mail']['smtp_port'] = 465;//这里是端口
$config['mail']['admin_mail'] = "用户名@gmail.com";
