Sure, but if that's the issue, you don't address it by messing around with individual mesage headers. Back in the day we sent compressed batches of messages over uucp. I expect something like that (or maybe exactly that) still works. > In addition, if a possibly-legitimate, possibly-phishing, > message comes along, I'd really like to see us (and our MUAs) > encourage users to look at headers, understand what can be > trusted and what can't, and so on.

That battle was lost over a decade ago. See for example the headers below that I took from a message that came through one of my mailing lists today. They'd be even longer if the message had started at Google's webmail rather than a MUN on the author's phone.
