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

The following steps will teach you how to change the MX Records of your domain, which are the mail server settings that indicate from where your incoming mail is routed.

To edit the MX Records 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, you must enter an IP address for your domain's MX Record instead.

Please note:
Changing your MX Records will change the servers which route your incoming mail. It is suggested not to alter MX Records unless you are sure of the changes as this can potentially cause mail delivery problems.
Step 1
Log in to your 1&1 Control Panel and select the relevant package.

Please note:
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 (similar to golf). You must enter at least two mail server addresses for the MX record.

  • Select Other mail server.
  • Enter the first mail server address into the MX 1 field followed by the mail server priority in the Priority field.
  • Enter the second mail server address into the MX 2 field followed by the mail server priority in the Priority field.
  • Repeat for the third and fourth mail servers if necessary, although only two records are required.

Please note:
All DNS changes, though live on the 1&1 Servers within minutes, may take up to 1 hour to be fully updated and recognised by all servers/computers on the Internet. If you are using your own name server, it may take up to 72 hours.
