"it was funny in a way that you wished a fire would break out"

Someone is currently sending spam with a return address of a sourceforge-based list I run. I'd say mailman-based, except sourceforge are (well, last I checked) somewhat behind the curve in terms of mailman versions, although I'm not even sure that being up-to-date helps since my general impression of mailman is that the developers are slowly learning all the things that Majordomo had baked into it after years of being the de facto standard. Anyway, one of the things sourceforge-mailman does is that when these spams bounce, it discards the bounce message. Hurrah. I certainly don't want to see it. But it then sends me an email telling me it discarded the bounce message. I've had several hundred of these show up over the last couple of days, and damned if I can find a way to kill them at source.

I suppose I could always set the list admin address to point to itself, or something equally nutty, and watch the server destroy itself.

updated: I looked over the wildly confusing over-featured admin panel again, and found

forward_auto_discards (privacy): Should messages from non-members, which are automatically discarded, be forwarded to the list moderator?

Note, this implies that automatic discards for members will still wind up in my mailbox. Thanks a bunch, Mailman.
