I haven't thought it through but, somehow, converting domains
in backward-pointing addresses (what do they do to/with
"Reply-to:"?) seems more, rather than less, offensive than
They turn Reply-To into a-labels too. Bah.
At least consistent.
Like you, I can guess why they are doing this (especially given
consistency). That doesn't make it less bad taste, more in the
spirit of the spec, or more use-friendly. But, coming back to
your original question, I think this is permitted and questions
about "wrong" or "broken" are matters of personal opinion.
