Adoption

fdm is available as a package in many Unix-like operating systems. It has been included in OpenBSD ports since 2007-01-18.^[1]

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]
