I have been doing some testing using an IMAP service (iCloud) I have noticed that different clients put things in different folders. some will put things in Sent, others will create a new Sent folder or Sent items. I think the same for deleted items.
So my question are:
1. Does the IMAP protocol define the folders that are uses or is it meant to be flexible ?
2. What about if I create my own folder every IMAP client meant be abLe to download them?
