[ih] No, really, I want to stay subscribed

Hi, Mark, et al.,

First, please forward me that email with headers intact. Can you also
send me the headers you receive for this message, to use as comparison?

FYI, the past instances of this issue all had headers indicating the
mail came from ISI, i.e., they looked exactly as they should if they
were generated by the Mailman system itself.

The header portion below is listed as coming from a 10-net address,
which shouldn't even be crossing the Internet, so I'm not yet sure what
it's evidence of.
