There is a procmail mailing list. It is not very active. List-Subscribe: <http://MailMan.RWTH-Aachen.DE/mailman/listinfo/procmail>, <mailto:procmail-requ...@lists.rwth-aachen.de?subject=subscribe> Procmail hasn’t seen any development effort in close to 20 years, with the last real update back in 1999, IIRC.

I think that is reject_unknown_reverse_client_hostname, but I also use: reject_non_fqdn_recipient, reject_unknown_sender_domain, reject_invalid_hostname,
