Kicking in backends works by sending a signal to the mail processes. It would be nice to support other ways also, but that would require larger changes.

If you change the dovecot.index.log of any of the folders where the user is IDLEing, that'd do it. I think just find /user 'dovecot.index.log' | xargs touch would work.
