Email suffix mx means

In the context of email, the suffix "MX" refers to Mail Exchanger records. These records are used to direct email traffic to the correct mail server for a domain.

In other words, when you send an email to a domain (e.g., [email protected]), the DNS (Domain Name System) looks up the MX records for that domain to determine where to forward the email.

Here's how it works:

1. The DNS looks up the MX records for the domain (example.com) and finds the IP address of the mail server responsible for receiving email for that domain.
2. The email is then sent to the mail server at that IP address.
3. The mail server processes the email and delivers it to the intended recipient's mailbox.

MX records are essential for email delivery, as they allow email clients and servers to route email correctly. They typically have the following format:

MX record = preference priority mail server

For example:

MX record = 10 mail.example.com

In this example, the MX record specifies that mail.example.com is the mail server responsible for receiving email for the domain example.com, with a preference value of 10.

There can be multiple MX records for a domain, each with a different preference value. The mail server with the lowest preference value is considered the primary mail server, and the others are considered backup mail servers.
