这是我的代码：
<?php
$to = 'test@hotmail.com';
$subject = 'reservation hotel n';
$msg ='ok';
// Make sure to escape quotes
$headers = 'MIME-Version: 1.0' . "'r'n";
$headers .= 'Content-type: text/html; charset=utf-8' . "'r'n";
$headers .= 'From: hôtel <reservation@hotel.com' . "'r'n";
mail($to, $subject, $msg, $headers);
?>
它适用于Gmail、雅虎、GMX。。。但它不适用于Hotmail/Live/MSN。
因为它适用于Gmail，我可以假设它与我的服务器无关，对吧？
我还试过：http://www.microsoft.com/mscorp/safety/content/technologies/senderid/wizard/Default.aspx
正在进行系统维护。请稍后再试。
think's for help
Check it
<?php
$to = "$email";
$subject = "Welcome to";
$message = " Hi $username,<br /><br />
Thank you for signing up with us.<br />
Thanks <br />";
// Always set content-type when sending HTML email
$headers = "MIME-Version: 1.0" . "'r'n";
$headers .= "Content-type:text/html;charset=iso-8859-1" . "'r'n";
// More headers
$headers .= 'From: <test@gmail.com>' . "'r'n";
$mail=mail($to,$subject,$message,$headers);
?>
使用php mailer 更改时解决的问题
require_once "class.phpmailer.php";
require_once "class.smtp.php";
$mail->Host = "smtp.gmail.com";
$mail->Port = 587;
$mail->Username = "**@gmail.com";
$mail->Password = "**";
$mail->From = "***";
$mail->FromName = "Hôtel **";
$mail->IsHTML(true); // if you are going to send HTML formatted emails
$mail->SingleTo = true; // if you want to send a same email to multiple users. multiple emails will be sent one-by-one.
//Caractéristiques du message
$mail->CharSet = 'utf-8';
$mail->ContentType = 'text/plain';
$mail->Encoding = '8bit';
$mail->Subject = "**";
$mail->Body = "okkk";
$mail->WordWrap = 0;
$mail->AddAddress("**@hotmail.com", "nom");
$mail->Send();
我认为您需要其中一个才能工作：发件人ID框架SPF记录向导
它应该可以解决你的问题，因为Hotmail希望这样做是为了安全。
