自从我移到新服务器以来，传出邮件滞留在垃圾邮件过滤器中 [英] Outgoing Listing-Mail stucks in Spam-Filter since I moved to a new Server

问题描述

以下问题：我已经通过PHP，SwiftMailer和Postfix编写了一个邮件列表。在我的旧服务器上，它可以正常工作，但是由于我移至另一台服务器（完全相同的配置，但其他IP），列表邮件卡在了接收者的垃圾邮件过滤器中。 （尤其是在Google Mail中）

Following Problem: I have written a mailing-list via PHP, SwiftMailer and Postfix. On my Old server it worked without any problems, but Since I moved to another Server (Exactly same configuration, but other IP) the list-mails stuck in the Spamfilter of the Receivers. (Espacially in Google Mail)

除了重新路由URL DNS记录（谷歌看到的是我就是那台服务器和邮件）外，我还有什么要做的吗是不是垃圾邮件？

Is there anything I have to do escept rerouting the URL DNS-Records, that Google sees, that "I am that Server" and the mail is no spam?

推荐答案

首先，请检查您的传出邮件服务器是否在HELO命令（或EHLO命令）中正确标识了自己当它连接到接收邮件服务器时。此名称还应该有一个A记录，该记录应指向邮件服务器的IP地址。另外，此IP地址应反向命名（可能但不一定与上述名称相同），并且该名称应指向邮件服务器的IP。如果上述任何一项都不正确，那么大多数垃圾邮件过滤器都不会将您的服务器视为真实邮件服务器，并且很可能会将您的服务器发送的所有邮件标记为垃圾邮件。这就是多少个垃圾邮件过滤器，可以阻止源自被视为僵尸的计算机的垃圾邮件。

First, check that your outgoing mail server is identifying itself correctly in the HELO command (or EHLO command) when it connects to a receiving mail server. There should also be an A record for this name that should point to the IP address of the mail server. Also, this IP address should reverse to some name (possibly, but not necessarily, the same name as above), and this name should point to the mail server's IP. If any of this is not right, then most spam filters will not consider your server to be a 'real' mail server, and will most likely flag any message sent from your server as spam. This is how many spam filters block spam that originates from computers that have been taken over as 'zombies'.

另一件事是检查您的邮件服务器IP是否为不在任何黑名单上。您可以为此使用MXToolbox： http://mxtoolbox.com/blacklists.aspx

Another thing to do is to check that you mail server IP is not on any blacklists. You can use MXToolbox for this: http://mxtoolbox.com/blacklists.aspx

您可以做的另一件事是使用port25的验证程序工具。此工具将发现可能导致您的邮件被标记为垃圾邮件的所有红色标记。请参阅 http://www.port25.com/support/authentication-center/email -verification / 了解更多信息。

Another thing you can do is use port25's verifier tool. This tool will spot any red flags that might be causing your messages to be flagged as spam. See http://www.port25.com/support/authentication-center/email-verification/ for more info.

最后但并非最不重要的一点是，您可能想为从中发送这些消息的域设置SPF记录，表示您的邮件服务器的IP已被授权从该域发送邮件。这将有很大帮助。有关更多信息，请参见：www.openspf.org。

Last but not least, you might want to setup an SPF record for the domain that you are sending these messages from, to indicate that the IP of your mail server is authorized to send mail from this domain. This will help a lot. For more info, see: www.openspf.org.
