Often you happen to jump through a couple of messages a couple of times shortly after each other, which would require to download the same message over and over again. Since this simply is a waste, Mutt uses a so-called header cache (hcache) to keep the most important bits of messages that it needs. This hcache is backed by a db-library, of which four flavours exist: ,   ,   and. If you don't have any preference yourself, pick gdbm or berkdb. Most likely you will have both already installed on your system. Enabling the USE-flags for more than one hcache backend will make Mutt choose one it likes best. It will always use at most one.
