spamassassin-dev: Is it possible to check HELO, rDNS or sender d

Is it possible to check HELO, rDNS or sender domain in RHSBL?

We subscribe to the Spamhaus Domain Block List (DBL). We use that as
part of a URIBL check which is nice, but they recently noted that it
would also be useful to run the DBL against the following items:

- Sender domain (MAIL FROM)
- HELO domain
- Domain in rDNS of sending IP

Blocking this stuff at SMTP stage in postfix would be straight forward,
but generally we prefer to be liberal in what we accept and score it in
SA instead.

However I don't think it's actually possible in SA to run any of the
above things against a RHSBL at the moment, or am I missing something?
