How To Configure Your Custom Domain Email, Step 3: MX Records, Method 2: Manually

Log into your GoDaddy account.
Select Domain Manager from the left-hand menu.
Click the name of the domain you want to map.
Click the “Total DNS Control and MX Records” link at the bottom of the section entitled “Total DNS.”
Expand the MX (Mail Exchange) section (if it’s not already) by clicking on the plus-sign.
Delete ALL of the existing MX Records! (Click the X on the right-hand side under the “Actions” section.) It’s important you get rid of ALL of the existing MX Records.
After you’ve deleted all of the MX Records, click Add New MX Record.
You will enter a total of 5 MX Records. For the first one, select 10 in the Priority Value drop-down menu. In the Enter a Host Name box, enter @. In the “Enter Goes To Address” box, enter ASPMX.L.GOOGLE.COM. (Make sure you include the period after com!). Enter a TTL value of 1 Hour. Click OK.
You’ll get a window comfirming that you’ve made a change.
Click OK and then click Add New MX Record again.
You’ll go through the same steps as before, but with different values, as shown below:
- Priority Value 20
- Host Name @
- Goes To Address ALT1.ASPMX.L.GOOGLE.COM.
- TTL Value 1 hour
- Priority Value 30
- Host Name @
- Goes To Address ALT2.ASPMX.L.GOOGLE.COM.
- TTL Value 1 hour
- Priority Value 50
- Host Name @
- Goes To Address ASPMX2.GOOGLEMAIL.COM.
- Priority Value 50
- Host Name @
- Goes To Address ASPMX3.GOOGLEMAIL.COM.
- TTL Value 1 hour
Note that the Total DNS Control and MX Records panel will show your MX Records as “pending.” That’s normal. It can take anywhere from a few minutes to a couple of days for all of the internet gnomes to do their thing and get it working.
Proceed to Configuring Thunderbird.
