I’d be surprised if there are many members on this list whose systems do not penalize connections from IP addresses without a fully confirmed reverse DNS entry one way or the other. Maybe I‘m wrong, but then I‘d like to hear from them.
I do not penalize such connections, in part because the systems I manage are hypersensitive to rejecting MS365 mail.
Also because it isn't useful. It IS useful to reject clients with no PTR and to match some name patterns in PTR results that are "generic."
