My fault, I think. I recently migrated to thunderbird from mutt, and
when I set up all my aliases (eg openssh@lakedaemon.net), I filled in
the Reply-To field. Apparently mindrot's list server doesn't rewrite
the Reply-To field. I've since fixed it for this alias.

I just took a quick look at it. While it operates in userspace, it
requires the fuse.ko module to be loaded, which would be a root level
activity, perhaps even a kernel module compile. I'll take a closer look
at it this evening.
I'm beginning to think more along the lines of ssh creating a local
virtual file and passing all operations on it to the remote file.
Unfortunately, since a file isn't a stream (it's fseek'able), this could
be difficult.
