php电子邮件 - 如何避免垃圾邮件结束垃圾邮件框 [英] php email - how to avoid mail ending up in spam box
问题描述
我的网站上有一个联系表，实际上是这样的：D
问题是邮件最终在垃圾邮件文件夹中。我试图用标题部分做东西，但似乎没有任何效果。
I have a contact form on my website, which actually works :D The problem is, that the email ends up in the spam folder. I have tried to do stuff with the header section, but nothing seems to work.
任何人都可以帮助我吗？

推荐答案
与PHP代码无关，确保电子邮件是从服务器上托管的域发送的。这意味着使用您的Gmail地址发送PHP将是一个坏主意。离开服务器的每封电子邮件都需要签名，并且需要有SPF记录。
It has nothing to do with the PHP code but make sure that the email are being sent from a domain that is hosted on the server. That means it would be a bad idea to use your gmail address for sending though PHP. Every email that leaves the server needs to be signed and needs to have SPF records
这通常是因为在DNS中没有设置正确的SPF记录。这可以根据您使用的软件轻松完成。如果你使用cPanel，那么这是一个两步的过程。
This is usually because in the DNS a correct SPF record has not been setup. This can be easily done depending on the software you use. If you use cPanel then this is pretty much a two step process.
