我的邮件作为垃圾邮件发送，我使用php mail（） [英] My mails are sent as spam, i use php mail()
问题描述
我有一个网站，向注册者发送一封邮件，而绝对不是垃圾邮件。事实是，我在PHP中使用了mail（）函数，但很多人将其作为垃圾邮件接收。
I have a website which send a single mail for those who register, definitely not spam. And the thing is that I use mail() function in PHP but lots of people receive it as spam.
$title = "title";
$body = "message";
$header = "MIME-Version: 1.0" . "\r\n";
$header .= "Content-type: text/html; charset=iso-8859-1" . "\r\n";
$header .= "To: ".$_POST["name"]." <".$_POST["email"].">" . "\r\n";
$header .= "From: SteamBuy <contacto@steambuy.com.ar>" . "\r\n";
mail($_POST["email"], $title, $body, $header, "-f contacto@steambuy.com.ar");
所以我想知道我在做什么错，以及如何解决。我不希望我的邮件显示为垃圾邮件，因为其中有些邮件可能包含有价值的信息。
So I want to know what am I doing wrong, and how can I fix it. I don't want my mails to appear as spam as some of they may contain valuable information.
推荐答案
重要的部分不是 mail（）本身，而是您托管网站的主机。因为您的电子邮件包含主机的所有相关信息-IP，等等。
The important part is not mail() per se, but the host you're hosting your site on. Because your email contains all relevant information of your host - IP, and so on.
由于大多数共享主机都使用一台主机，因此用户数量众多托管在单个服务器上，大多数/某些用户可能想使用 mail（），因此电子邮件提供商可能会将主机的IP列入黑名单。这意味着您的网站已包含在该黑名单中。
Since most shared hosts, I assume you're using one, have a ton of users hosted on a single server, and most/some may want to use mail(), email providers may blacklist the IP of the host. Which means your site is included in that blacklist.
使用共享主机时无法解决此问题。
There is no way around this issue when using a shared host.
