OTRS is currently the only tool we have to verify permissions from third-party copyright holders, but most uploaders are not even aware it exists. In the "Release rights" step of the UploadWizard, when "This file is not my own work" is chosen, it currently says:
The copyright holder published this work with the right Creative Commons license
Not all Creative Commons licenses are good for this site. Make sure the copyright holder used one of these licenses.
[license options]
(Messages mwe-upwiz-license-cc-head and mwe-upwiz-license-cc-subhead.)
Change that to:

- If the copyright holder wants to release the work under that license via e-mail please follow the steps described at COM:OTRS and add {{subst:OP}} to the source field above.

(Could override mwe-upwiz-license-cc-subhead in Wikimedia Messages; a radio button label should not be too long.)
