So I changed config of users@ for bounce :
bounce_info_stale_after => lowered to 3
bounce_score_threshold => raised to 30

I do not think that's gonna fix much, but at least, it should reduce the
number of time people get disabled ( ie, people would need to bounce for
a full month to be disabled I think )
