I am looking at com.day.cq.workflow.impl.email.EMailNotificationService, and i want on complete of task, the workflow complete notifications to be sent to users from an email address keyed in on the "Day CQ Workflow Email Notification Service" and not from the from.address set in "Day CQ Mail Service" in com.day.cq.mailer.DefaultMailService. Any help?
