I use sqlgrey on CentOS 5.4 with postfix. Simple to install and flexible configuration. Because I use catch-all e-mail, I enabled greylisting for everything except my regular e-mail addresses. So mail from any sender to my regular e-mail addresses arrives without any delay. Why catch-all? Because I often use the part before the "@" as a key to see the origin of the e-mail when subscribing. Why greylist? Stop most stupid spammers Why sqlgrey? Actively maintained, well documented, small in size, sqlite database option and I can select what domains and e-mail addresses to greylist or not. Disadvantages? The version in Centos 5.4 is old and sqlgrey is written in Perl. So it might consume too much cpu and memory for very busy server, although the website states that it can be used for servers recieving millions of mails per day. Note: On a busy server, I would recommend using the MySQL or PostgreSQL database option of sqlgrey. There is a web based management interface at http://www.vanheusden.com/sgwi/ Did not test it as it is easy to manage sqlgrey with your favourite sqlite tool (sqlite3 cmd line, sqliteman, sqlitebrowser). Bas.
