Not really, this item->callback is not the user callback, is the
callback that is set when calling tny_camel_queue_launch, that is, the
callback that the camel queue will call once the asynchronous operation
is finished.

In the case you mention add_msg_async the callback that it's called is
tny_camel_folder_add_msg_async_callback. This callback "unpacks" the
AddMsgFolderInfo and finally calls the user callback with the user data.
