I responded to a new list announcement today and got the following headers back:
 
Reply-To: [log in to unmask]
Sender: [log in to unmask]

To: <@uconnvm.uconn.edu:[log in to unmask]>
X-Listprocessor-Version: 9.1 -- List Server by Sunnyside Computing, Inc.
X-Comment: The CPSR Internet Library
 
I can understand the run-of-the-mill host using an email address of
"listserv" for their listproc software, but shouldn't the author(s) of
listproc be aware of the copyright violation?
