freebsd.org does not care if your reverse DNS mapping points back to
the name you identified yourself with, it only checks that the name
the server IDs itself as when submitting email resolves to the correct
IP address.

Many people (including me) have a working setup where reverse DNS
mappings do not give back the original hostname we ID with.
