DNS Setup for Network Solutions
Log in to your Network Solutions account and select Domain Name on the left side menu.
Select your desired domain name (if you only have one domain, you will be taken directly to the Domain Details page). On the Domain page, go to Advanced Tools.
Click "MANAGE" next to Advanced DNS Records.
On the Manage Advanced DNS Records page, to create a new record click the +Add Record button.
Set the record type to CNAME.
On the Refers to drop-down menu, select Other Host.
Enter the Hostname for the CNAME record you are adding which is given on your SMTP2GO account's "Sending > Verified Senders > Sender domains" page and click on your domain.
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. E.g. em123456
Enter the Value we provide for the CNAME record into the Alias field.
TTL can be left as-is or set to a default of 7200.
Click the Add button to save the changes.
Repeat steps 3 and 4 for each required CNAME record.
