Remove specific emails from sendmail mqueue

How do I remove emails from mqueue based on destination address. Needing to remove deferred messages going to "" Due to an endless loop (that has been found and corrected) I have a huge amount of emails deferred or qued for retry in var/spool/mqueue. Need to clear these out ASAP as the bounceback messages are filling up my var/log folder space by 1G every 20min. There is legit email also in the que so can't just empty var/spool/mqueue. How do I filter to just the results I am looking for? And, do I need to stop sendmail first?
