There are various spam sinks that people have created where they
welcome spam because it gives them data to analyse. At least there
were - I can't remember any now.

But if you just want an address which is bound to fail and not cause
anyone else any hassle then use something like foo at bar.invalid

The important bit is the .invalid - from rfc2606:

This will fail at the first hurdle because the DNS resolver will
know it is invalid without even doing any lookups.

But as others have said, there must be better "solutions" than
forwarding to an invalid address.
