I am trying to find out if there is any way to remove an Email service, as I can see no obvious way to do so.
This has become an issue because I have created a package that contains an Apex class that handles email messages.
I install the package in a development environment and create an Email service that uses that Apex class. Everything works ok until I want to uninstall the package. I can't because the Apex class is being used by the Email service, but I can't delete the Email service.
