I assume you're talking about unidentified spam delivered to an
over-quota mailbox.  Intentionally bouncing spam, such as a with an
after-queue or delivery time spam filter, is a very bad idea and
will eventually get you blacklisted as a backscatter source.

You can control how long a bounce stays in the queue with the
bounce_queue_lifetime parameter, default is 5d (5 days).
