success := imap.Login('myLogin','myPassword');
if (success <> 1) then
  begin
    ShowMessage(imap.LastErrorText);
    Exit;
  end;

//  Create the new email folder (sub-mailbox) on the IMAP server.
//  If no folder path is provided, the new folder is a sub-mailbox of Inbox.
success := imap.CreateMailbox('newFolder');
if (success <> 1) then
  begin
    ShowMessage(imap.LastErrorText);
    Exit;
  end;

//  (In GMail, folders are called "labels".
//  This example would create a new "label" in GMail.)

//  Now create a sub-folder under "newFolder".
//  Make sure to use the proper separator char for your IMAP server.
//  The separator char used here is "/".   It is typically "/" or ".".
//  The SeparatorChar property contains the separator char
//  that should be used for the current IMAP session.
success := imap.CreateMailbox('newFolder/subFolder_A');
if (success <> 1) then
  begin
    ShowMessage(imap.LastErrorText);
    Exit;
  end;

ShowMessage('Success.');
