It uses a mysaql backend and is written in C. Unless you don't wanna hear about mysql, that should be the one to chose. otherwise, both sqlgrey and postgrey have their fans. some other servers are listed on http://spamlinks.net/filter-server-greylist.htm#implement-postfix It may be worth noting that gld has had very bad vulnerabilities in the past. I'm not sure it's safe to use.
