Hello,

I'm trying to change privileges to /Sent folder. User cannot remove messages for /Sent folder, by:

# zmmailbox -z -m user@domain.com mfg /Sent all rwi
# zmmailbox -z -m user@domain.com gf /Sent
{
"color": "defaultColor",
"contentSequence": 1,
"defaultView": "message",
"flags": "i",
"grants": [{
"permissions": "rwi",
"type": "all"
}],
"id": "5",
"imapItemCount": 254,
"imapMODSEQ": 26987,
"imapUIDNEXT": 4249,
"imapUnreadCount": 0,
"isCheckedInUI": false,
"isExcludedFromFreeBusy": false,
"isSyncEnabled": false,
"isSyncFolder": false,
"isSystemFolder": true,
"itemCount": 254,
"name": "Sent",
"parentId": "1",
"path": "/Sent",
"pathURLEncoded": "/Sent",
"size": 38188656,
"subFolders": [],
"unreadCount": 0
}

But this is not working... I can still remove files from Sent folder.
How can I do this protect user /Sent folder?

Regards,
