DNS Setup for ISPConfig3
Log in to your ISPConfig account. Go to the DNS tab and click on your desired domain.
To create a new record, go to the Records tab and click the CNAME button.
Enter the Hostname we recommend into the Hostname 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 Target Hostname field.
Leave the TTL value to its default and make sure the Active checkbox is checked.
Click the Save button.
You can find the "Name" and "Value" under the Settings > Sender Domains section of your SMTP2GO Dashboard.
Repeat step 2 for each required CNAME record.
