Do CNAME records also forward MX requests?

由 ▼魔方 西西 提交于 2019-12-22 01:26:50
问题 My DNS has a set up for the domain base.com that consists of A and MX records. There are several other domains that are set up with CNAME records, pointing to base.com. Do I need to set up anything special (like extra MX records) for the CNAME domains, or will the CNAME records also forward any MX requests. Example: Will an email sent to info@otherdomain.com be delivered correctly to the MX of base.com if these (and only these) DNS records are in place: ; A and MX set up for base.com base.com

linux dig命令 转

dig 命令主要用来从 DNS 域名服务器查询主机地址信息。 查询单个域名的 DNS 信息 dig 命令最典型的用法就是查询单个主机的信息。 $ dig baidu.com dig 命令默认的输出信息比较丰富，大概可以分为 5 个部分。 第一部分显示 dig 命令的版本和输入的参数。 第二部分显示服务返回的一些技术详情，比较重要的是 status。如果 status 的值为 NOERROR 则说明本次查询成功结束。 第三部分中的 "QUESTION SECTION" 显示我们要查询的域名。 第四部分的 "ANSWER SECTION" 是查询到的结果。 第五部分则是本次查询的一些统计信息，比如用了多长时间，查询了哪个 DNS 服务器，在什么时间进行的查询等等。 默认情况下 dig 命令查询 A 记录，上图中显示的 A 即说明查询的记录类型为 A 记录。在尝试查询其它类型的记录前让我们先来了解一下常见的 DNS 记录类型。 常见 DNS 记录的类型 类型 目的 A 地址记录，用来指定域名的 IPv4 地址，如果需要将域名指向一个 IP 地址，就需要添加 A 记录。 AAAA 用来指定主机名(或域名)对应的 IPv6 地址记录。 CNAME 如果需要将域名指向另一个域名，再由另一个域名提供 ip 地址，就需要添加 CNAME 记录。 MX 如果需要设置邮箱，让邮箱能够收到邮件，需要添加

How do I disable HTTPS on Heroku

由 こ雲淡風輕ζ 提交于 2019-12-20 17:28:24
问题 I created a site and put it on Heroku. I then added a custom domain (e.g. "site.example.com") in the Heroku control panel and I pointed the DNS to my Heroku address. This works fine, but when I visit the site, I get a big browser warning, saying the certificate is for herokuapp.com, not for "site.example.com". How do I turn off HTTPS or fix it in some other way? (I don't need my own SSL certificate for the site.) Note : It's not Heroku's fault if your app is forcing people onto SSL. Check

Subdomain of website for Github pages project

由 瘦欲@ 提交于 2019-12-20 10:26:41
问题 I have a Github project, github.com/jeti/matrix , and I set up a "Github pages" site for the project so that it is accessible here jeti.github.io/matrix/ . That is all configurable through Github. Now, I would like to add a subdomain of my personal website so that the website is accessible via the subdomain matrix.jeti.io of my website jeti.io . I am just really confused how to do that because the documentation don't seem to show how to redirect a project page to a subdomain. I have tried a

Cloudfront CNAME vs DNS CNAME

由 荒凉一梦 提交于 2019-12-18 11:45:46
问题 I've set up a distribution but I'm a bit confused about the purpose of the CNAME that can be set up in Cloudfront. Assuming my assigned Cloudfront domain is d27fwrff25jcfdafa.cloudfront.net I can assign the "nice" CNAME static.example.com using the AWS Management Console. I don't understand why I'd want to do this though. Why wouldn't I just create the CNAME in my sites DNS records and point it directly at d27fwrff25jcfdafa.cloudfront.net instead of creating the CNAME in Cloudfront? This is

java运用JDBC技术实现对表的查询 第一步：导包 第二步：注册驱动: DriverManager调用一个方法注册驱动 第三步：创建Connection 连接对象 ; 调用DriverManager 的一个方法 第四步：创建Statement 对象 第五步：调用statement对象的查询方法, 得到一个结果集对象 ResultSet (想象成一个集合,里面有我们查出来的数据); 第六步：遍历ResultSet结果集,获取数据,打印. 第七步：关闭Connection连接 代码如下： public class Demo1_Jdbc { @Test public void test01() throws SQLException { try { //1.注册驱动: DriverManager调用一个方法注册驱动 DriverManager.registerDriver(new Driver()); //2.创建Connection 连接对象 ; 调用DriverManager 的一个方法 Connection connection = DriverManager.getConnection("jdbc:mysql://localhost:3306/day07", "root", "root"); //3.创建Statement 对象, Statement statement =
