No answer required
If you close a ticket originating from an incoming email and you did not fill the 'E-Mail' dialog todo4teams will ask you if you really don't want to send a reply email:
To suppress this question (e.g. for emails sent automatically by technical systems or coming from no-reply adresses) add a property named "NOANSWERREQUIRED" to the task, see below:
task.addProperty("NOANSWERREQUIRED","TRUE");
