为什么我不能向Hotmail发送电子邮件？ [英] Why can't I send an email to Hotmail?
问题描述
这是我的代码：
$boundary = sha1('whatever');
$headers = 'MIME-Version: 1.0'."\r\n";
$headers .= 'From: "Domainname" emailname@domain.com'."\r\n";
$headers .= 'Reply-to: Domainname <emailname@domain.com>'."\r\n";
$headers .= 'X-Priority: 3'."\r\n";
$headers .= 'X-Mailer: Mail 1.0'."\r\n";
$headers .= 'Subject: '.$subject."\r\n";
$headers .= 'Content-Type: multipart/alternative; boundary="'.$boundary.'"'."\r\n\r\n";
$message = '--'.$boundary."\r\n";
$message .= 'Content-Type: text/plain; charset="utf-8"'."\r\n\r\n";
$message .= $text."\r\n";
$message .= '--'.$boundary."\r\n";
$message .= 'Content-Type: text/html; charset="utf-8"'."\r\n\r\n";
$message .= $html."\r\n";
$message .= '--'.$boundary.'--';
mail($email, $subject, $message, $headers);
它适用于Gmail，Yahoo，GMX ...但它不适用于Hotmail / Live / MSN。
It worked for Gmail, Yahoo, GMX ...but it didn't work for 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？
Because it worked for Gmail, I can assume that it has nothing to do with my server, right?
我也尝试过：
mail('username@hotmail.com', 'This is a subject', 'This is the body');
同样的问题。它甚至不会发送到我的垃圾文件夹。
Same problem. It doesn't even get send to my junk folder.
推荐答案
旧答案：
Hotmail阻止没有SPF记录的域。您可以制作一个此处
Hotmail blocks domains without an SPF record. you can make one here

截至2015年6月，常见要求是：
As of June 2015, common requirements are:
1）DKIM在Exim中启用DKIM现在是减少电子邮件被标记为垃圾邮件的机会的重要工具。强烈建议您为您的域启用DKIM。
1) DKIM Enabling DKIM in Exim is now a very important tool to reduce the chance of your emails being flagged as spam. It's highly recommended to enable DKIM for your domains.
2）SPF记录与-all而不是〜全部
2) SPF record with -all instead of ~all
3）DMARC记录以帮助远程服务器决定如何处理失败的DKIM / SPF消息。
3) DMARC records to help remote servers decide what to do with failed DKIM/SPF messages.
4）通常情况下，a）像发送IP的反向IP查找，b）正确查找该rDNS值，最好指向相同的IP，c）主机名上的MX记录。
4) The usual things, a) like reverse IP lookup on sending IP, b) forward lookup on that rDNS value preferably pointing to same IP, c) MX record on hostname.
示例：
"v=spf1 a mx ip4:1.2.3.4 -all"
其中1.2.3.4是您的服务器的IP。
Where 1.2.3.4 is the ip of your server.
