[clo-devel] trac ticket mailing lists not working?

Just noticed that the trac ticket mailing list doesn't seem to be working for cmucl. According to the list archives (cmucl-ticket), the last ticket emailed was in June 2011. But there have been more tickets created or modified since then, but I haven't received any emails about them. Is it a config problem for cmucl, or does it affect other projects? Ray
