[MM3-users] Discard all mail with the subject "The resutls of your email commands"

Hello, I am using mailman 3.2.1 for several mailing lists. My colleagues want me to stop all mails with the subject "The results of your email commands". I found some contributions here, but nowhere a solution for this question. Does anybody has any suggestion? Maybe I could try to handle this outside of mailman, but then I would have to pass this task on to someone I dont know .... :-( Thanks for all hints. :-) Wolfgang
