MX Record - What is...

MX Records (Mail Exchange) are DNS records that are used to route email to email servers. You can have numerous MX Records posting to different email servers to prevent loss of email due to downtime. Email is sent to servers pointed to in MX records based on Priority which states that the lowest the Priority number the higher the priority of the server. Emails will be routed to MX records of 0 first.

Just one doubt instead of MX Records we can use the CNAME Record for the same as you said in your early lecture, then what is the need for MX Records??

[FahadSumar]

That was really helpful. Thanks Eli for such a simple and clear explanation. 🙂

[movetolinux]

Does a "hole" in the series of the numbers for MX server's priority pose any security risks? Ie. 0, 1, 2, 3, 4 better than 0, 10, 20, 30, 40 ?

[thissagardevkota]

Hey, Thanks for the explanation, I have a question,
I have a mail server on priority 10. (first server)

Now I have another mail server, let's make its priority 20. (second server)

When will the mail second server (priority 20) get the mail?
As you told it will be there if the higher priority server goes down.

Can the second server will get the mail if the recipient email address is not on first server?

can you teach also Spf and dkim? what are used for thanks

1:45 If MX is an IP address of machine that is receiving mail for you, what DNS record tells the address of a server that is sending your mail? SPF?
