I think it might be helpful if someone would name or describe a largish

AOL famously uses the second received header to filter mail from
providers that are too large to block but too lazy or incompetent to
do proper outbound filtering on their users' mail.
Can you describe (or refer to a description) of what was done in sufficient
technical detail that we can evaluate whether or not whatever gets proposed
here would break that functionality, and also whether there was any other way
to accomplish the same purpose? I don't doubt that this story is true, and
worth considering, but at the level of detail you've provided, it's just a
story.
