The RFC describes otherwise ... e.g. a new protocol, which would
connect to a new daemon.  An extension to an Email client can still
connect over to port 4190 to do the ManageSieve thing.

Doing that via a web site, which can also support a few canned scripts
or script options, probably is a better route.  But our internal web
server is still on the to-do list, so that's gonna wait, here.  In the
mean time, I just need a short term solution to divert tagged-as-spam
messages into the INBOX-spam (or something like that) folder.  I'll
probably just go ahead and write a shim program in C (as easy for me
as a script is for others) to check for the tag and add the -m option
to deliver as needed.

I guess for now I'll be leaving this out.  I don't want to be a
vacation backscatter source.
