The linked email didn't actually have NML_ADSP_CUSTOM_MED. The ADSP rules are a way of punishing mail from certain domains for not having DKIM_VALID_AU, so if you find them together you've found a bug. ADSP is an obsolete forerunner of DMARC, and in practice the ADSP hits are based on the override entries in 60_adsp_override_dkim.cf. The custom levels can only be set by an override so NML_ADSP_CUSTOM_MED really has nothing to do with ADSP.
