Edit/Change the Domain's Mail Servers (MX Record)

The following steps will teach you how to change the MX Record of your domain, changing the mail server that your incoming mail is routed to.

Before completing the following steps, it is suggested that you review our Explanation of MX Records.

Please note:
Changing your MX Records will change where your incoming mail is routed! It is suggested not to alter MX Records unless you are sure of the changes as this can potentially cause mail delivery problems for days.

To edit the MX Record you must supply at least two mail server addresses. The addresses must be domains or subdomains and cannot be IP addresses. If you are only able to access your mail server via its IP address, please follow the guide on how to Enter an IP Address for a Domain's MX Record instead.

Step 1
Log in to your 1&1 Control Panel and select the relevant package.
Step 2
Click Domain Center from the Domains panel.
Domains > Domain Center
Domains > Domain Center

Step 3
Click the arrow icon next to the domain name in question to display an options menu. Domain center home page

Step 4
Select Edit DNS Settings from the Domain Settings section of the options menu. Domain center home page

Step 5
You will not be able to edit the MX record for your domain unless you are using the 1&1 name servers. If you are using a CNAME record or other DNS, you will not be able to make a change to the MX records within the 1&1 Control Panel and will need to make this change with your current DNS host.

Please note that mail server priority is usually set in multiples of 10 with the lowest number taking top priority (kind of like golf). You must enter at least two mail server addresses for the MX record.

  • Select Other mail server from the MX Records section.
  • Enter the first mail server address into the MX 1 / Prio text box followed by the mail server Priority in the second text box.
  • Enter the second mail server address into the MX 2 / Prio text box followed by the mail server Priority in the second text box.
  • Repeat for the third and fourth mail servers if needed although only two addresses are required.

Click the Save button to save your changes.

A confirmation page is displayed informing you that the changes will be updated accordingly. As with all DNS changes, it may take up to one hour before the changes are recognized by all servers/computers on the Internet.
