MX Record – What is…

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.

    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?

    I mean, I have 1@example.com, 2@example.com …. 10@example.com on the first server (priority 10). will the mail sent to 11@example.com be delivered to second server (priority 20)?

  17. Advance64 on November 14, 2021 at 11:47 am

    Hey Eli, Iโ€™ve learned that you can only put in domain names as mx records and no ip addresses. Is that true?

  18. fire fox on November 14, 2021 at 11:48 am

  21. Rahul banerjee on November 14, 2021 at 11:50 am

    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??

  22. SecurityVlogger on November 14, 2021 at 11:51 am

    Beautifully succinct. Thank you Eli.

  23. Kornelije Kovac on November 14, 2021 at 11:58 am

    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?

  24. Pablo Medina on November 14, 2021 at 12:03 pm

    Bro your awesome

    ‘nslookup -type=MX 2subdomain.1domain’ (mail_username@2subdomain.1domain)

  27. Jukka Paulin on November 14, 2021 at 12:07 pm

    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 ?

  28. Bailey Harrison on November 14, 2021 at 12:08 pm

    Why does every service on the internet use a normal dns a record yet email uses mx?

  29. SoundDrGenie on November 14, 2021 at 12:08 pm
