One of our customers is using the functionality to manually let their support personel "accept" a new customer in Service:
The problem is that they have a contact form on their web page that they want to import information from. The form sends an email which then gets imported into superoffice, but the from-adress needs to be set to a value in the form (an email-field). As it is, it currently uses the email address that is set as the form-sender address (firstname.lastname@example.org).
What field can I change with a trigger so that the above functionality lets the service agent create a new user based on the value I set in the trigger?
