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 would not suggest anyone start on procmail now, and I say this as someone who uses procmail. > Secondly, is there a way for postfix to reject mail from unresolvable domains > (e.g.: reverse lookup of 1.2.3.4 returns unknown, please reject). I think that is reject_unknown_reverse_client_hostname, but I also use: reject_non_fqdn_recipient, reject_unknown_sender_domain, reject_invalid_hostname,
