I started to suspect that as I composed the question. On the other hand, I just subscribed to an open office announcement list by sending an email, and got this back as the subscribe address they got: [email protected]. I wonder how I will unsubscribe?? Maybe they use the sender field to make sure they are not getting spoofed subscriptions requests?
