Not exactly. There are 2 distinct domain lists internal to SA that exist

1. The URIDNSBL 'skip' list of domains which are ignored in body URIs.
These are known to not *per se* have any correlation to the ham/spam
classification decision.
IIRC the basic policy for this list is "these domains are never going to
be listed in the major DNSBLs, so don't bother looking them up because
the result will ALWAYS be negative".
If you're brushing the edges of the free lookup limits, this may also
help you stay under those limits a bit longer.
