Only proper E-mail client I found  but some issues 1. Hierarchical folders are flattened to an oversized list of all folders. Very bad when there are hundreds or thousands of year/month/day folders under some topics. The good part is that K-9 does not lump together all my e-mails in a """"""""""""""""unified inbox"""""""""""""""" and doesn't send my e-mails to any server but my own.""
