[otrs] notifications' sender

Hi. We need to get all outbound emails sent by agents appear in the mailbox. I'm aware of the BCC feature, but we have some rights restrictions among agents, and this means all of them will see all sent emails, which is not an option. I set up a notification with the text of a sent email, but it's always sent by OTRS Notification Master. Is there any way to insert a variable somewhere so that we could see an agent's name as sender (not in a subj or body)? Or any other suggestions? Cheers, Ilya
