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, > This is not documented because, at the moment, we only like to tell > people that are actually having a problem about it.

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.
