Hello

Is it OK to vent a dryer vertically into an attic crawl
space instead of horizontally thru an exterior wall to the
outside? - paul

Generally I would say no. There may be some exceptions where that craw
space is vented a lot better than most and you live in a dry environment.
Otherwise, you are going to add moisture to an area you want to keep as
dry as possible. Vent to the outside. I might add that you would also be
depositing lint down there.

there is NO good reason to vent the dryer in the attic no matter what.

it may not immediately destroy your house, but there is still no good reason
to do it.
