I haven’t yet found a way to disable certain lists, but you can add certain signatures to whitelist.
See https://docs.mailcow.email/manual-guides/ClamAV/u_e-clamav-whitelist/#whitelist-specific-clamav-signatures
Important thing here is to add signatures formatted {Source}.{List}.{sig ID} and nothing else.
i.e. I had this signature found Sanesecurity.Jurlbl.00dada.UNOFFICIAL(f7fed2cf934df7a306097dd9f81b4e0f:3294807)
from which I had to add Sanesecurity.Jurlbl.00dada
exactly.
There has to be a better way, I would like to know.
