[Mailman-Users] Auto-discard notifications?

[Skip Montanaro]

I get the occasional message from Mailman (2.1) with the subject
"Auto-discard notification" and an attached mail which was discarded.  The
message offers no explanation for why Mailman discarded it.  After looking
through the bounce and filter pages of the admin interface, it doesn't seem
that either applies.  (Both pages suggest that I should get a reason along
with any messages forwarded to me.)

Any pointers would be appreciated.
