Pic is too tiny - I can't see if you have sales's sent folder mounted in jan's account - much less any other folder name
At the moment the on-behalf is completely automatic & doesn't need personas to do it.
Example:
Create 5 accounts (well I know you can't but bear with me)
1) Shared
2) User1 -manager of shared's inbox & sent
3) User2 -viewer of shared's inbox & sent
4) Test1
5) Test2
Send message from user1 to test1 (or user2 to test2) and both user1 & user2 can see the sent mail - best if you're using conversation view so it's shown when not in the shared sent folder and working in shared inbox.
Zimbra will show this as 'sending on behalf'
The headers look like:
From:
shared@domain.com (so to test1 or test2's perspective it's shared sending the email)
Sender:
user1@domain.com (so yes test1 or test2 can technically view the mail headers and see which person sent it if not using ZWC - some mail clients may display this)
To:
test1@domain.com
You'll want to keep an eye on how this will change slightly in
Bug 22819 - reply to another user's message is always on-behalf-of (The ability to grant others 'on-behalf' sending permissions, and associated option to always send 'on-belalf' or not when replying in shared folders, and/or drop-down choice when sending.)
Bug 19146 - send on behalf of for delegate access for ZWC Bug 27259 - Option for "On behalf of sent mail" to go to "on behalf of" user's sent items
Might also watch
Bug 25875 - allow user migration or remapping of reserved folders on ZWC Not the main intent, but we used to have zimbraPrefSentMailFolder (which chooses where the sent mail is stored) per options > identity (or what we call preferences > accounts > persona today) in 5.0.x it had been removed on identities when re-vamped
Bug 17320 - Next rev of (mail) identities preferences management (server side) so thus you can't have multiple anymore (ie create a persona in jan@ for sales@ & store sent mail in sale's sent) you can only have one per user.
