DNS Setup for SoftLayer
Create a Sender Domain as per the instructions here.
Log in to your SoftLayer account.
To create a new record, go to the SoftLayer Name Servers section. Select your appropriate domain and click the Edit button.
Enter the Hostname we recommend into the Host field.
Note: You may only need to add the first part of the recommended hostname and not your full domain name to your DNS records as your provider may automatically add it.
Enter the Value that we advise for your CNAME record into the Points to field, then click the Update Zone Record button.
You can find the "Hostname" and "Value" on the Sending > Verified Senders > Sender domains section of your SMTP2GO Dashboard.
Repeat steps 2 and 3 for each required CNAME record.
