Procmail Mail Filtering Language

http://www.procmail.org/ftp://ftp.procmail.org/pub/procmail/

The Procmail mail filtering language, written by Stephen van den Berg of Germany, lets you filter hundreds or thousands of incoming mail messages per day according to a predefined set of rules. The Procmail language understands details about most UNIX mail transport and delivery agents, giving you the platform to write custom mail filtering scripts. The Procmail filtering engine can be invoked by Sendmail or by a user's .forward file.

See procmail(1), procmailrc(5), and procmailsc(5) for more information on using procmail. Extensive examples are provided in procmailex(5).

The Infinite Ink Web site (http://www.ii.com) contains pointers to documentation, examples, and FAQ, and provides a link to the FTP site where you can obtain the Procmail kit.

Pure-FTP Server

http://www.pureftpd.org/

File Transfer Protocol (FTP) is a client/server protocol that allows a user on one computer to transfer files to and from another computer over a TCP/IP network. An anonymous FTP account on your system allows any remote user to log in to your system using an FTP or anonymous user name. Once logged in, that user can access a special directory hierarchy that contains publicly accessible files and can transfer those files to another system using FTP.

Squid Proxy/Caching Server

http://squid-cache.org

Squid is a high-performance proxy/caching server that supports FTP, Gopher, and HTTP data objects. Squid tends to be faster than other proxy/caching servers because it maintains linked objects in RAM, caches DNS lookups, and supports nonblocking I/O, negative caching of objects, and DNS lookups. Squid documentation and FAQs are available from the Squid homepage.
