how to block spam to commits-owner at projects.openmoko.org?

[Aapo Rantalainen]

Ok, this issue is not solved yet. Now I got spam to
XXX-commits-bounce at projects.openmoko.org

In mailinglist options there are [Bounce processing].
There are many 'yes'-ticks, I really do not understand what all of
them means. I just disabled the first "Should Mailman perform
automatic bounce processing?".
