我目前正在设置新的VPS，所以我的电子邮件不会进入垃圾邮件文件夹（即Gmail，Hotmail等）。 为了实现这一切，需要正确设置所有的DNS / SMTPconfiguration。 使用mail-tester.com我已经完成了其中的8.2个，其中有一个我无法解决的问题。
你可以在这里find我的邮件testing结果： http : //www.mail-tester.com/web-dWaMuK
问题：
-1 FSL_HELO_BARE_IP_2 IP used in the HELO request The hostname must be a domain name, not an IP-address -0.865 RCVD_NUMERIC_HELO Received: contains an IP address used for HELO 我有一台运行在CENTOS 7.1上的TransIP VPS，带有一个WHM / cPanel设置。
我经历了几个教程来正确设置，这是我迄今为止所做的：
根据一些谷歌search的答案将是build立一个主机名作为rDNS（我做了），但由于某种原因，它仍然看到IP。
我忽略了什么？
PS标题和邮件testing器报告中的rDNS仍然需要刷新到正确的rDNS（charlotte.studiomod.us）。 但即使它刷新到正确的rDNS，我仍然得到同样的错误。
这是电子邮件的标题显示的内容：

具有数值HELO的Received头不是Exim提供的HELO头。 Exim正在发送charlotte.studiomod.us 。
被抱怨的HELO是您用来发送邮件的程序所提供的HELO：roundcube。
从邮件中只selectReceived邮件标题可以让你更容易看到：第一行是邮件testing程序的内部邮件testing程序，第二行是邮件testing程序说它从夏洛特邮件（格式是HELO（rDNS [IP]），第三是夏洛特说它从roundcube得到的邮件，最后一个是唯一一个说helo是IP地址的。
