exactly Julius bounce is descriptive also a good word around this too, my English is unfortunately not very well knew not as I it to be better described can.
But I meant exactly to be rerouted/redirect/bounce a message can.
as complex the realization would not be unfortunately white I so quite where I set is. Ingenious would be to be realized naturally with plugin api as core_plugin.
not interest, interesting exists is the feature for example also around a Spam filter to train in the man Spam to learns also from other RoundCube users at the feature reroutes.
Would be beautiful if this as feature for a coming version would be planned and to the Road map be taken up could.
Stop is regarded depending on to what extent the feature as meaningful and like large the interest of the RoundCube Community to it is.
