phpPHPMailer报错？

Charset="UTF-8";$address="2069667008@qq.com";$mail->IsSMTP();//使用smtp方式发送$mail->Host="smtp.163.com";//你的企业邮域名$mail->SMTPAuth=true;//启用smtp验证功能$mall->Username="xxx@163.com";//邮箱用户名$mail->Password="xxx";$mail->Port=25;$mail->From="aaa@sohu.com";$mail->AddAddress("$address","a");$mail->Subject="发的标题";$mail->Body="内容 hello,world";if(!$mail->Send()){	echo "邮件发送失败 
";	echo "错误原因".$mail-ErrorInof;	exit;		}echo " 邮件发送成功";?>

Warning: Creating default object from empty value in D:\apache2.4.10VC9\Apache24\htdocs\PHPMailer\test.php on line 10
邮件发送失败

Catchable fatal error: Object of class PHPMailer could not be converted to string in D:\apache2.4.10VC9\Apache24\htdocs\PHPMailer\test.php on line 21
这是哪里错了
版本：PHPMailer_5.2.4 php版本是php-5.4.32

回复讨论(解决方案)

echo "错误原因".$mail-ErrorInof;
改成
echo "Mailer Error: " . $mail->ErrorInfo;

$mall->Username="xxx@163.com";//邮箱用户名
改成
$mail->Username="xxx@163.com";//邮箱用户名

$mail->SMTPDebug提示出错
SMTP -> ERROR: RCPT not accepted from server: 553 5.7.1 : Sender address rejected: not owned by user tomcat_boy@sohu.com

去下载个PHPMailer 包吧！里面什么都很齐全，自己改变些内容，然后记得开通邮件端口
