Click on the email address you want to forward emails from.
Set Up Email Forwarding
Navigate to the Forwarding tab.
Check the box for Enable email forwarding.
Enter the email address(es) where you want emails to be forwarded. You can specify multiple email addresses.
Click OK to save your changes.
Tip: You can also set up an email address without creating an actual mailbox while configuring forwarding simultaneously:
In the left-hand menu, go to Mail and click Create Email Address. Enter the desired email address for the domain and deselect the options for Plesk Login and Mailbox. Make sure to generate a password to avoid error messages.
