Well it didn't take long for the automated reply:

Dear Friend: [ <--- Notice the personalization ]

I will respond in writing to your specific concerns as soon as possible. Please make sure you have also included your mailing address with your email. [Now isn't this a stupid comment. My email address is in the headers of the email I sent the guy. And somehow the tenses just don't seem correct for this post hoc suggestion.]

Apparently you haven't seen this before - it's not as stupid as you think.
He's asking for your mailing address, not your e-mail address.
They do that to avoid sending paper (via USPS) to people outside their district.
