View sent emails by persona's X-Authenticated-User

[justanoob]

Hello, Zimbra forum:)

I am a new and happy admin of ZCS 8.8.9, So far, so good. The only problem I have is as follows. We have several 'team-mailboxes' that I have shared between users (5-6 users per team) using 'shared mailboxes toolkit' zimlet. I was able to create personas for each user and I can send emails with proper X-Authenticated-User header. All groovy. But my users complain that they cannot distinguish who did answer the email.
I need to be able to see who sent ('who' meaning X-Authenticated-User) emails when viewing 'sent' folder of the shared mailbox. How can I do it?
