Because this probe is sent from the list domain, it does not bounce and the member stay subscribed. The other way to alleviate it is to raise the limit of days of bouncing before unsubscribing someone. As long as people with p=reject don't contribute much to a list, then it is all fine, you are not passing the thresholds where mailman thinks all the members at gmail, yahoo, hotmail,... are not there anymore due to too much bouncing. http://www.gnu.org/software/mailman/mailman-admin/node25.html I suspect setting bounce_you_are_disabled_warnings to >0 could help on this list.
