# Command class for carrying out the actual incineration of the `InboundMail` that's been scheduled 
# for removal. Before the incineration – which really is just a call to `#destroy!` – is run, we verify
# that it's both eligible (by virtue of having already been processed) and time to do so (that is, 
# the `InboundEmail` was processed after the `incinerate_after` time).
