发邮件的问题，有做过的请进！
第一种:$to = "[email protected]";$subject = "Test mail";$message = "Hello! This is a simple email message.";$from = "[email protected]";$headers = "From: $from";mail($to,$subject,$message,$headers);echo "Mail Sent.";===================================第二种require 'class.phpmailer.php';try {$mail = new PHPMailer(true); //New instance, with exceptions enabled$body = file_get_contents('contents.html');$body = preg_replace('/\\/','', $body); //Strip backslashes$mail->IsSMTP(); // tell the class to use SMTP$mail->SMTPAuth = true; // enable SMTP authentication$mail->Port = 25; // set the SMTP server port$mail->Host = "smtp.126.com"; // SMTP server$mail->Username = "[email protected]"; // SMTP server username$mail->Password = "luo11111"; // SMTP server password$mail->IsSendmail(); // tell the class to use Sendmail$mail->AddReplyTo("[email protected]","First Last");$mail->From = "[email protected]";$mail->FromName = "比翼网";$to = "[email protected]";$mail->AddAddress($to);$mail->Subject = "First PHPMailer Message";$mail->AltBody = "To view the message, please use an HTML compatible email viewer!"; // optional, comment out and test$mail->WordWrap = 80; // set word wrap$mail->MsgHTML($body);$mail->IsHTML(true); // send as HTML if(!$mail->Send()){echo "Message could not be sent.
";echo "mailer error: " . $mail->errorinfo;exit();} else {echo "message has been sent";}} catch (phpmailerexception $e) {echo $e->errormessage();}启动sendmail后，发出的邮件在垃圾邮件里？
=====================================================================------解决方案--------------------sendmail成功后，要用接收程序才能接收到，我机子上的是qmail，你的就不知道了。
------解决方案--------------------启动sendmail后，发出的邮件在垃圾邮件里？
有可能是接收邮件的邮箱有相关的过滤设置，这些设置可能是用户自己定义好的，也可能是邮箱默认就定义好的。造成的结果就是：当某一类邮件或者某个用户的邮件发送到目标邮箱后，目标邮箱自动识别其为垃圾邮件，并将其删除或者放在回收站中，这样你看到的当然就是垃圾邮件了，------解决方案--------------------第一种肯定不好, 你自己sendmail做smtp服务器不会被其他邮件服务器信任，用126的做smtp肯定不容易被认为垃圾邮件了。
------解决方案--------------------$mail->issendmail(); // tell the class to use sendmail这句去掉。
------解决方案--------------------垃圾邮件没法控制------解决方案--------------------更换ip
