Email suffix mx stands
The MX (Mail Exchanger) record is a type of DNS (Domain Name System) record that specifies the mail server responsible for accepting email messages on behalf of a domain.
In other words, the MX record tells the world which mail server is responsible for receiving and processing email messages sent to a particular domain.
Here's a breakdown of the MX record:
MX
stands for "Mail Exchanger"- The record consists of two parts:
Preference
(a numerical value): This determines the order in which mail servers are tried when sending an email. A lower preference value means the mail server is tried first.Mail Server
(a hostname or IP address): This is the hostname or IP address of the mail server responsible for accepting email messages for the domain.
For example, if you have a domain called example.com
, your MX record might look like this:
MX IN 10 mail.example.com
MX IN 20 mail2.example.com
In this example:
- The preference value is 10, which means
mail.example.com
is tried first. - The mail server responsible for accepting email messages is
mail.example.com
. - The preference value is 20, which means
mail2.example.com
is tried second. - The mail server responsible for accepting email messages is
mail2.example.com
.
When an email is sent to example.com
, the sending mail server will look up the MX record for example.com
and try to deliver the email to the mail server with the lowest preference value (in this case, mail.example.com
). If that mail server is unavailable, the sending mail server will try the next mail server with the next lowest preference value (in this case, mail2.example.com
).
I hope that helps!
