That would work for a single backend machine, but not for multiple
machines.

If there's no managesieve proxies, then I imagine my best bet will be
to modify avelsieve to be able to determine which backend server to
connect to.  In the short run, I think avelsieve also has an option to
connect to a different server.  That should be sufficient for testing
purposes.
