How do we configure or change the 'From' address on delivered email notifications such as W4 exempt

We are using delivered process for Determine Exempt W4 which sends automatic email notifications to employees with Exempt W4 status for Federal. The concern is the delivered notification looks to be from the server ID (i.e. hcmprd@qhcmprcs08.xx.abc.edu or hcmprd@phcmapp06.prod.abc.edu) so recipients of the email don't want to open the email for fear of a phishing email or scam. We would like to change the from email address on these delivered notifications so users know it's a legitimate email from HR. I'm hoping this is a simple configuration that we can make. Please let me know if anyone using delivered workflow notifications to employees have successfully made modifications. Thank you for your time and consideration of this question.
