score_sender_maps for From address?

Hi,

I'm trying to implement per-user allowlisting. Users don't always have
their own home directory, making it very difficult to do it in spamassassin.

I'm using amavis-2.13 on fedora40 and would like to allowlist some senders,
but the envelope sender is often obscure or unique or sent from a general
mailing service like Mailchimp, etc, which makes it very difficult to use
the envelope sender.

How can I implement the equivalent of the welcomelist in spamassassin in
amavisd instead?
