na pas transmettre les cancels?

Bonjour,
En attendant une solution plus pérenne, je vois dans inn.conf une option qui pourrait peut-être convenir (voir plus bas). Dans mon cas il ne s'agit pas de refuser l'annulation des spams, mais le principe est le même (à priori le filtre cyberspam est déjà activé mais non valide ici)
est-ce faisable sans tout casser?
merci

     Whether to refuse all articles whose message IDs start with <cancel.. This message ID convention is widely followed by spam cancellers, so the vast majority of such articles will be cancels of spam. This check, if enabled, is done before the history check and the message ID is not written to the history file. This is a boolean value and the default is false.
     This is a somewhat messy, inefficient, and inexact way of refusing spam cancels. A much better way is to ask all of your upstream peers to not send to you any articles with cyberspam in the Path: header (usually accomplished by having them mark cyberspam as an alias for your machine in their feed configuration). The filtering enabled by this parameter is hard-coded; general filtering of message IDs can be done via the embedded filtering support.
