FYI: AOL blocked my null Return-Path confirmations

I noticed that an email from an AOL user was still in my pending queue.
Looking into it with a friend's AOL account I could see that the
default qconfirm generated email with a <> Return Path wasn't delivered
to her account.

Changing that by editing the .qconfirm/msg/request file allowed for the
confirmation email to go through.  This is described in
  http://smarden.org/qconfirm/bounces.html

Just an FYI for others wondering why people aren't responding to the
confirmations.
