Some of our NetSuite clients noticed emails being sent from ‘system@netsuite.com’ instead of their preferred address ‘john.doe@mycompany.com’.
Solution
The reason for this is that they might not have configured your DKIM settings in NetSuite yet.
NetSuite clients set up DKIM (DomainKeys Identified Mail) right away to ensure emails appear to be sent from the correct address.
A user with an Administrator role or a user with the Full level of the Set Up Company permission can enter email domains in NetSuite. NetSuite generates the necessary information for you to create and publish two CNAME records in DNS for each domain and for each subdomain from which you want to send email.
