This legacy seems to constrain how HELO would be used with respect to
signatures by the Submitter,
since Helo has nothing to do with the submitter (from/sender) the issue is not
"constraint" but irrelevance.
if someone is trying to relate submitter and helo, they need to stop.
as there is less support allowing this
field to be dynamic.
ahh, now the question of whether mta implementations give as much freedom to
set the helo field is another matter entirely. my understanding is that,
indeed, they do not.
