The moderation UI provided by Mailman 2.1.14, the version Mozilla uses (note: I don’t know if this is the latest version, and I don’t know if this UI is still present) looks like this. The controls for an individual message are as in this screenshot:
What is should look like is something like this:
|Subject||Sender||Spam Score||Reject and Blacklist||Accept and Whitelist||Reject||Accept||Defer|
|***SPAM*** Regarding Your Online Accountfirstname.lastname@example.org||4.4|
