We have a trigger that creates a task for inbound email replies to existing cases. Currently, the task that is created has a subject line something like "An email reply has been received". This is stored as a system label.

Instead, I want the code to assign the subject line of the email to the task subject.

Any idea how I get the emails subject line, to replace the code seen below?

All help greatly appreciated.

 for (Integer i : emailIds) {
    if(((String)cases.get(trigger.new[i].ParentId).ownerid).startsWith('005')) { // no tasks for cases that are still assigned to a queue, only users
      Task t = new Task(Subject = System.label.Custom_Case_Email_Task_Subject,
                whatid = trigger.new[i].parentId,
                activitydate = Date.today()
                );
      
      // Assign task to the Level 1 Case Owner Id if it exists          
      if(cases.get(trigger.new[i].parentid).Level1_Case_Owner_Id__c == null) {
        t.ownerid = cases.get(trigger.new[i].parentid).ownerid;
      } else {
        t.ownerid = cases.get(trigger.new[i].parentid).Level1_Case_Owner_Id__c;
      }
      emailMsgsWithTasks.add(i); // note that this email has associated task, to update below.
      tasks.add(t);
    }
  }
