Like any other e-mail, the e-mail for task completion is delivered to the recipients mentioned in the To, CC and BCC fields. This task is assigned only to the To recipient(s). Though the task is not assigned to the CC and BCC recipients, any one of them can complete the task or assign it. However, when a CC or BCC recipient completes or assigns a task, a warning to that effect is recorded in the bpserver.log file.
