I've hit a major obstacle: We have our maildirs on a Netapp, nfs
mounted with root squash, and everything owned by a single
unprivileged user. Exim is running as euid 0, uid for "exim" and the
path/to/Maildir/ is mode 700 all the way up, and maildirsize is mode
600. It would appear that unless I remove root squash for my mail
servers, my only option is to have a cheap daemon running as that
unprivileged user which will simply listen on a port for a command, do
the calculation, and return the answer.

Dammit. I'm right back where we were before I started experimenting.
