2 things need to be in place:

- The mailbox you want to have cleared out needs to have the 'expire'
  annotation set.  Easiest way is via cyradm, e.g. to set an expiry of
  30 days on joebloggs Trash folder.

  cyradm> mboxcfg user.joebloggs.Trash expire 30

- The cyr_expire command needs to be running in the EVENTS section of
  cyrus.conf.  I have:

    delprune      cmd="cyr_expire -E 3" period=1440

  Which causes the expired messages to be deleted every 24 hours.
