I would need something that is sieve only, as Dovecot is already
installed, configured, and running.

I'm also considering writing a program to be run by Postfix in place
of "deliver", which will read the mail to determine how to run
"deliver".  As long as mail comes in on stdin and is written on
stdout, it should be relatively easy (pipe(), fork(), maybe setsid(),
execve() in child, read() and write() in parent).  But this would take
some thorough testing to be sure it is safe.
