Someone who has local access to the server filesystem can locate them in
the LISTSERV spool directory and delete them.  Be sure to review each
one individually (with notepad, for example), don't just delete
everything you may find in there.

A list was put on hold and 76 messages are now queued up. The list
owner
wants to release the hold, but not have those messages posted/sent? Is
there
a way to flush/delete them?
