所有邮件都去了垃圾邮件SPAM(sendmail on centos)127.0.0.1问题？

SPF CHECK http://www.openspf.org/Why更新：

SPF检查为我提供了这样的信息：启用SPF的邮件服务器拒绝了声明信封发件人地址为[e-mail]的邮件.启用S​​PF的邮件服务器收到来自ourdomain.com(x.x.x.X)的邮件,该邮件声明信封发件人地址为[e-mail].域名ourdomain.com已授权ourdomain.com(x.x.x.x)代表其发送邮件,因此该邮件应已被接受.我们不可能说出它被拒绝的原因

更新：我正在使用Google Apps从中发送电子邮件和接收电子邮件.也许这有助于研究我们的问题.我们只有用于设置Gmail的MX记录,现在认为这可能是个问题吗？如果邮件服务器收到来自www.ourdomain.com的电子邮件但无法找到该IP的MX记录,那可能是坏的或不是？

我们所有邮件都转到gmail垃圾邮件文件夹.
邮件不是垃圾邮件或笨重,只是来自我们的网络应用程序的注册确认电子邮件.

SPF标题给了我以下内容

Received-SPF: pass (google.com: best guess record for domain of [e-mail] designates x.x.x.x as permitted sender) client-ip=x.x.x.x;
Authentication-Results: mx.google.com; spf=pass (google.com: best guess record for domain of [e-mail] designates x.x.x.x as permitted sender) smtp.mail=[e-mail]
Received: from www.ourdomain.com (localhost [127.0.0.1])

其中x.x.x.x是我们的完整IP地址

UPDATE
我的完整邮件和标题现在是：

ps：我设置了正确的SPF记录,允许我们的x.x.x.x ip发送电子邮件

更新：

我们如何确保谷歌不会将我们视为垃圾邮件.我已经读过gmail会收到来自@ ourdomain.com的电子邮件,它会运行一个nslookup或者其他什么来查看我们是否真的设置了接收MX服务器？

有人可以确认这一点并给我一个我可以测试的nslookup命令.我很困惑,因为在ourdomain.com上的nslookup提供了正确的MX记录,但是WWW.ourdomain.com上的mxrecord并没有.

我们发送的机器的主机名是www.ourdomain.com.
这可能是个问题吗？

你改变了主机名吗？如果服务器的主机名是localhost,localhost.localdomain,包含IP地址或无法解析到您的服务器,则会出现此问题.改变它：
hostname yourdomain.com以及/ etc / sysconfig / network.

重新启动sendmail然后telnet到端口25上的服务器,应该说：
220 yourdomain.com ESMTP Sendmail,如果不是,您可能还需要编辑sendmail配置文件.

一般情况下,我发现您会因以下原因之一而被垃圾邮件：

>主机名错误(如上)
>没有反向DNS
>没有SPF记录
>你被列入黑名单(Google for blacklist checker)
>您正在发送垃圾邮件.

祝好运.
