This doesn't work for most people, but I had fun composing this
response, and coming just a few weeks after people claiming that
IP-based blacklists work well, and rarely result in false positives, I
felt I just had to share. :-)

Hi there. Your mailer appears to have my one of the addressed used by
primary mailhub, 69.25.196.31 (it reverse-resolves to
www.church-of-our-saviour.org.). Its primary ip address and hostname
is thunk.org, 69.25.196.29. You can see who I am here:
http://thunk.org/tytso
If you use any amount of Linux on your systems, I am the first North
American Linux Kernel developer, and the maintainer of e2fsprogs, the
filesystem utilities for ext2/ext3/ext4. This bounce took place
because I replied to some user who apparently has a mailbox on
gondor.apana.org.au, on the Linux Kernel Mailing List.
The way I see things, I provde *way* more services to your users than
you do to me, so I don't see any reason to place an international
phone call to get my IP address un-blacklisted. If one of your users
or one of your staff members needs my help to fix a Linux kernel
problem, or to unscramble an ext2/3/4 filesystem, or an invite to the
some future Linux Kernel Summit, and they can't receive my e-mail,
that is *your* problem, not mine.
I've arranged to make sure this gets routed via an mit.edu mailhub,
but that's about all I plan to do to resolve this problem.
Your move.
