Did you set `use-package-always-ensure' to a non-nil value?  It might be
that use-package is trying to install the package
{dired,stmpmail}-async, even though these are just libraries, part of
the async package.

Also, I don't think it is necessary to configure all of these
separately, at least in your case.
