Multi MX record with one DNS server.

Post by hack3rcon » 2020/10/13 19:26:22

Hello,
I have some questions about email server and MX record:

1- Each URL can have a MX record?

2- If a company need multi MX record then it must have multi DNS server too? For example, a company have two websites, "example1.net" and "example2.net", if that company need "info@example1.net" and "info@example2.net" emails, then company need two DNS servers?

Thank you.

1. URLs don't have MX records

2. No, one DNS can serve multiple domains and offer multiple MX records.

It is good practice to have more than one DNS server to serve your zone, preferably on different subnets served by different ISPs otherwise when you patch and reboot your DNS server, no-one will be able to look up your entries.

Thank you.
For sending and receiving emails from the Internet with Postfix and Dovecot, then I need a MX record? The A record can't help me?
