Drying Machine Conduct

The duct is joining an insulated duct and then go outside. Can it be a problem? A lot of humidity comming off the duct on the maconry. Normaly insulated duct for dryer should be in attic? no?

It can be insulated, but it has to be of the right dryer vent approved material. For example, it cannot be the flexible duct used for HVAC.

Thank you for the reply.
