I have an old message stuck somewhere. The recipient's address is invalid and the system keeps trying to re-send despite mail output queue being supposedly empty. Any ideas where I should look for the stuck message?
~$ mailq mailq: Mail queue is empty ~$ sendmail -bp sendmail: Mail queue is empty
My /var/log/mail reads:
