Did you read the man page Mail::SpamAssassin::Conf entry for
whitelist_from_rcvd? Do you understand that the second argument to
it -must- be a valid rDNS name?

If you look at the entries in 60_whitelist.cf, you'll see things
like 'yahoo-inc.com'. A nslookup on yahoo-inc.com works.

If I do a 'nslookup haggis.' I get an error message, not a successful
DNS lookup.

Note that it must be a valid rDNS, so take the name, look up the
address, take the address lookup the name and see if final name
matches the initial name.

Also take note that 'trusted_networks' must be set correctly
for whitelist_from_rcvd to work.

Yes, you can use whitelist_from instead of whitelist_from_rcvd, but
whitelist_from is trivial for spammers to abuse.
