$domain is a per-recipient variable, so it is not set when there are no
recipients (outside a mail transaction or in the MAIL ACL) or when
there are multiple recipients (in the pre or post DATA ACLs and in the
local_scan function and at transport time).

What you need is some way of turning the list of recipients into a local
user under which to run SpamAssassin. This is usually not easy. One way is
to add a check to your recipient ACL to defer later recipients that have
different filtering requirements from earlier recipients. I don't know
how safe this is in practice.
