Is this right?

validates_uniqueness_of :email, :message => “Email taken”, :unless =>
:email == ‘[email protected]’

no. :unless must be the name of a method that returns whether or not
to run the validation

How would I write a condition that doesn’t check the uniqueness of a
mail address if the address is ‘[email protected]’

you write a method that returns true if the email is that magic value

Unless I am severely mistaken, you can’t use :unless as a condition in
the validation anyway. It would need to be :if => some_condition,
where the some_condition method would return true/false.

It worked with :unless, as described in the API.
