A "legal" notice sent by email isn't worth the paper it's written on.
I would remove the copyrighted material in question, notify the author
that you have done so and wait for a proper summons. If practical,
find the author's email address, phone number or snail mail address by
independent means. You have no way of knowing if the email you got was
in fact from the author's representative. Could be a forgery.

I'm not aware of any special protection for mailing list archives.
