大多数发件人验证使用不同的 DNS 条目，并且不以任何方式依赖 A 记录，因此您应该可以很好地进行更改。
You should be fine changing the root record. Whenever an email comes in it will always look at the MX records. There are two things to check though.
The MX records will point to a domain name, are they pointed at the root domain? Secondly do they use any form of webmail? You might need to create another record such as mail.example.com in order to ensure that they can still access these two things.
Most sender validation uses different DNS entries and doesn't rely on the A records in any way so you should be fine changing things.
例如，我有一个托管在服务器上的网站，并且有用于电子邮件的 Google Apps。我所做的只是将 MX 记录插入我的托管提供商，我的电子邮件就没有问题了。
Should be just fine to change the A records and leaving the MX records intact.
For example, I have a website hosted on a server and I have Google Apps for email. All I did was insert the MX records into my hosting provider and my emails went through no problem.

您应该可以很好地更改根记录。每当收到电子邮件时，它都会查看 MX 记录。但有两件事需要检查。
MX记录会指向一个域名，它们是否指向根域？其次，他们是否使用任何形式的网络邮件？您可能需要创建另一条记录，例如 mail.example.com，以确保他们仍然可以访问这两个内容。

正确的。 A 和 MX 记录彼此不相关，因此不会相互影响。您可以将它们指向不同的域。
Correct. A and MX records are not related to each other and will therefore not have an impact on each other. You can point them to different domains.

更改 A 记录并保持 MX 记录不变应该就可以了。
