HashCash is supported in spamassassin versions 3.0 and upwards. Spamassassin is probably the most popular antispam system for mail servers so it should be widely supported.


I could not find a php library for hashcash but wordpress does have hashcash support and it is written in php. See http://elliottback.com/wp/archives/2005/10/23/wordpress-hashcash-30-beta/
