Since there are others in the distribution who use Fastmail,
I note that Fastmail has a hidden feature to change these headers.
According to my correspondence with a Fastmail senior support agent,

If you want to know how to avoid getting that header, you can contact
support or ask me.

My friends comment often that my mail is marked as spam, so, upon
reading this, I thought, does the absence of the earliest received
header cause the mail to be marked as spam? Upon further though,
I concluded that, maybe it contributes, because commercial spam
processing seems so arbitrary these days, but it's not the main cause.
My mail was getting marked as spam for years before I had Fastmail
remove this received header. I suspect that the main suspicious feature
of my email is that it is not Gmail.
