Fortimail GUI System Quarantine delete all messages in specific mailbox

Hi guys,

sorry for the trivial question... but is it possible to delete all messages from a specific mailbox in the system quarantine at once over the GUI?

Im not so sure what happens, when I select a mailbox and hit that delete button... its like very confussing so does it delete the entire mailbox when I do this, or does it delete the message content of the selected mailbox?

Obviously I can run the command in the console to delete the messages, but im just curious about this. When I switch in the specific mailbox, there is like no way over the GUI to select all messages at once.

Thanks
