Sendooway is a multi-user and multi-target ESMTP proxy that acts as mail transfer agent. Instead of configuring SMTP servers and authentication data for every mail identity on every device, it allows you to configure them centrally. Sendooway automatically uses the correct smarthost, logs on with the user's account data, and sends their mail.
PHProxyImproved is a Web proxy script based on PHProxy beta 2. It features a user friendly admin module with logging, file size control, banning by IP, and on-site ADS. A Google Translate widget enables language accessibility for international users. Plugins are user scripted, which can provide access to a greater range of websites such as YouTube. The main proxy fully supports The Pirate Bay with both torrents and magnet links.
The Apache Traffic Server (TS or ATS) is a modular, high-performance reverse proxy server, generally comparable to Squid. It was created by Inktomi, and distributed as a commercial product called the Inktomi Traffic Server, before Inktomi was acquired by Yahoo!. Traffic Server has been actively used inside of Yahoo for over 4 years, serving billions of requests every day. As of fall 2009, Traffic Server is an Open Source project, and in April 2010 the Apache Traffic Server was promoted to a top-level project of the ASF.

Mireka is a mail server with SMTP, Mail Submission, and POP3 services. It can also be used as an SMTP proxy. As a proxy, it can help to prevent or diagnose mail problems, like outgoing backscatter spam. It provides detailed logging, basic mail traffic statistics, tarpit to prevent email harvesting, and loop detection. It can filter email by DNSBL, SPF, mail size, local domains, and recipients list. Local recipients can be specified using regular expressions. TLS is supported for incoming connections. Aliases, forward lists, and very simple mailing lists can be configured in XML. Custom filters and other components can be written in Java, and they can be easily implemented and installed.
KnProxy Lambda is a branch of KnProxy that uses Java and PHP to provide users with a safe and balanced proxy service. Communications between the Java client and the PHP based server are encrypted in highly secure encryption methods. Traffic is also distributed among many servers to prevent flow monitoring. KnProxy Lambda allows users to set up a full proxy processing POST, GET, and AJAX Requests on any server offering PHP. It is also compatable with APJP servers, allowing for a wider network and an easier migration.
Surrogate is an HTTP proxy functioning in both forward and reverse proxy modes. It is written in Erlang OTP and uses stream filters for inspecting and modifying data as it passes through the proxy. Additional stream filters can be implemented by writing modules that implement the filter_stream behavior. Reverse proxy features include load balancing. Additional balancer methods can be specified by implementing modules with the gen_balancer behavior. Forward proxy features include gzip compression to end servers, CONNECT support, and an HTTP proxy with authentication that can use MySQL or Mnesia backends. There is also a SOCKS 4/5 proxy listener.
