It's a lightweight, fast and reliable Sendmail milter that implements a real-time Sender e-Mail Address Verification technology. This technology can stop some kinds of SPAM with a spoofed sender's e-Mail address. Also it implements a real-time Recipient e-Mail Address Verification technology. It can be useful if your machine is a backup MX for the recipient's domains or if your machine forwards all e-Mail messages as a relay host for your domains to another internal or external e-Mail servers. It's a lite alternative for the spamilter, milter-sender and milter-ahead milters.

pxytest is a command line utility to test a host for open proxies that are vulnerable to spammer abuse. It is written in perl. Unsecured proxies currently are the most significant conduit of junk email. This is a particularly vexing problem, because open proxies, unlike open mail relays, hide the origin of the spam, making it impossible to trace. This utility tests a host to see if it is vulnerable to such abuse. See http://www.unicom.com/sw/pxytest for more information. pxytest was written by Chip Rosenthal.

This plugin implements logging functionality for your webmail interface. You can choose to log to a database, a file, your system log, or any combination thereof. You can also choose which kinds of events to log, including login events, logout events, login error events, all outgoing messages, possible outgoing spam messages, and other error events. Also included is monitoring functionality that will send alert emails to the administrator when certain events trigger. If you use the timeout_user plugin, logout events caused by user timeouts will be captured. Log message format is also completely custom-defined to meet your needs in the configuration file.

This is a simple sendmail milter which adds an X-RBL-Warning header to any emails that are received that come from an open relay as determined by your choice of RBL checking service (i.e. bl.spamcop.net). This is useful if you'd rather have the mail user agent (MUA) deal with potential spam rather than just blocking it in case you loose legitimate messages. Note that the X-RBL-Warning header is only set if the site was found to be an open-relay.

FlowViewer, FlowGrapher, and now FlowTracker are tools that provide an easy web-based user interface for selecting, viewing, graphing, and now tracking NetFlow data stored using Mark Fullmer's flow-tools software. The user is able to filter data (inclusion or exclusion) by device, IP address range, port, router interface, autonomous system (AS), specified time interval, and now by protocols, TOS field, and TCP flags. Many of the flow-tools reports are configured as drop-down selections. Users are also able to save reports and graphs for later viewing.
