Mail Avenger is a highly-configurable, MTA-independent SMTP server daemon. It lets users run messages through filters like ClamAV and SpamAssassin during SMTP transactions, so the server can reject mail before assuming responsibility for its delivery. Other unique features include TCP SYN fingerprint and network route recording, verification of sender addresses through SMTP callbacks, SPF (sender policy framework) as a general policy language, qmail-style control over both SMTP-level behavior and local delivery of extension addresses, mail-bomb protection, integration with kernel firewalls, and more.

Greylisting is a new method of blocking significant amounts of spam at the mailserver level, but without resorting to heavyweight statistical analysis or other heuristical (and error-prone) approaches. Consequently, implementations are fairly lightweight, and may even decrease network traffic and processor load on your mailserver. Greylisting relies on the fact that most spam sources do not behave in the same way as "normal" mail systems. Although it is currently very effective by itself, it will perform best when it is used in conjunction with other forms of spam prevention. For a detailed description of the method, see the Whitepaper. The term Greylisting is meant to describe a general method of blocking spam based on the behavior of the sending server, rather than the content of the messages. Greylisting does not refer to any particular implementation of these methods. Consequently, there is no single Greylisting product. Instead, there are many products that incorporate some or all of the methods described here.

EchoWare® enables any peer-to-peer or client-server application to utilize a "packet relay server" approach in order to achieve end-to-end connectivity without adjusting any intervening firewalls, proxies or NAT'ing routers. Via echoWare, all the application's data connections appear to the network as "outgoing" connections to the same TCP port of the echoServer.
