IF the list-owner sets a certain topic in the Topics= keyword in the
list's control file (let's say that one of the topics is GARBAGE), then
you could set your own subscription options by sending SET <listname>
TOPICS ALL -GARBAGE .  You'll then get all messages except those that have
GARBAGE: in the subject header.  Of course, this also depends on message
senders obeying the convention of putting GARBAGE: in their message subject
headers when appropriate.
