The documentation for whitelist_from_rcvd shows examples like this:

What if the sending server has no rDNS?
They you can't use whitelist_from_rcvd, and the sender needs to fix
their rDNS!
Is there a way to use this feature with a numeric IP instead of a rDNS
domain?
No.
If so, what is the syntax?
If they are adamant that they can't fix rDNS, I usually ask for an SPF
record, and then do a whitelist_from_spf. When they claim that they can
fix neither rDNS or set their SPF record, I might use amavisd-new's
soft-whitelisting to trim a couple of points, or I tell them to pound
sand. Usually I can convince people to fix one or the other.
