Remarks
Deliberately not canonicalised. RFC 9493 Section 3.2.2.1 records that email canonicalisation is not standardised and that a receiver cannot know the sending provider's algorithm, so it puts the choice on the receiver: apply the algorithm your own mail system uses. Folding case here would silently answer that question on the receiver's behalf and destroy the original. EmailCanonicalization offers the one transformation the specification does settle, to be applied when comparing rather than when storing.
