Maildroid Folder Issues

I've just started using Maildroid on my SE X8 and I'm having some trouble setting up my imap folders. The inbox and sent messages folders are working fine and are syncing fine with my server but when I save a message as a draft, or delete a message, it only goes into the local drafts or deleted messages folder on the phone rather than on the server. Is there a way to correct this within the Maildroid settings?

Thanks Martin
