Variable: nnml-nov-is-evil
nnml-nov-is-evil is a variable defined in nnml.el.gz.
Value
nil
Documentation
If non-nil, Gnus will never generate and use nov databases for mail spools.
Using nov databases will speed up header fetching considerably.
This variable shouldn't be flipped much. If you have, for some reason,
set this to t, and want to set it to nil again, you should always run
the nnml-generate-nov-databases command. The function will go
through all nnml directories and generate nov databases for them
all. This may very well take some time.
This is a Gnus server variable. See Info node (gnus)Select Methods.
