Ya... looks like the listserv strips them. :(

Here is an example that I sent to gmail (afaict gmail.com does not yet
distinguish between insecure and secure domains):

Received-SPF: pass (google.com: domain of scott () cse ucdavis edu
designates 128.120.246.11 as permitted sender) client-ip=128.120.246.11;
Authentication-Results: mx.google.com; spf=pass (google.com: domain of
scott () cse ucdavis edu designates 128.120.246.11 as permitted sender)
smtp.mail=scott () cse ucdavis edu; dkim=pass header.i=@cse.ucdavis.edu
