I think, probably, I need to subscribe with a different e-mail address. 
But previously I had a problem using my domain address, too. My address 
<mitch@accidentalexpert.com> states an x-sender of mstone@accidentalexpert.
com (the account name) -- and apparently that's what the am-info list 
server looks at instead of From. When I needed to unsub a couple of months 
ago, I found that I could not, because I wasn't "really" a subscriber. 
What a royal pain in the butt.
