 ‘nnmh’ is just like ‘nnml’, except that is doesn’t generate NOV
 databases and it doesn’t keep an active file or marks file.  This makes
 ‘nnmh’ a _much_ slower back end than ‘nnml’, but it also makes it easier
 to write procmail scripts for.
 
    Virtual server settings:
 
 ‘nnmh-directory’
      All ‘nnmh’ directories will be located under this directory.  The
      default is the value of ‘message-directory’ (whose default is
      ‘~/Mail’)
 
 ‘nnmh-get-new-mail’
      If non-‘nil’, ‘nnmh’ will read incoming mail.  The default is ‘t’.
 
 ‘nnmh-be-safe’
      If non-‘nil’, ‘nnmh’ will go to ridiculous lengths to make sure
      that the articles in the folder are actually what Gnus thinks they
      are.  It will check date stamps and stat everything in sight, so
      setting this to ‘t’ will mean a serious slow-down.  If you never
      use anything but Gnus to read the ‘nnmh’ articles, you do not have
      to set this variable to ‘t’.  The default is ‘nil’.
