In 2014, the last maintainer of procmail posted a message to an OpenBSD mailing list himself suggesting that he removed the procmail port,[3] it had been suggested by a well-known OpenBSD ports maintainer that fdm is the natural alternative[4] (the procmail port,[5] however, had not been removed and remained in place as of 2020).
fdm is listed on the OpenBSD Innovations page, in the section of projects maintained by OpenBSD developers outside of OpenBSD.[2]
