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-directorynnmh
directories will be located under this directory. The default
is the value of message-directory (whose default
is ~/Mail)nnmh-get-new-mailnil, nnmh will read incoming
mail. The default is t.nnmh-be-safenil,
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.
