XamimeLT is an email scanner which encapsulates your existing sendmail or Postfix server setup. It scans both incoming and outgoing email. It can scan for email viruses, unwanted file types (eg. EXE, BMP, MPEG) and file names (eg. prettypark.exe), spam, and almost anything you care to search for in an email. It can also be used to scan for text snippets within emails and to insert disclaimers into outbound emails. XamimeLT was formerly known as "Inflex".
Saké Mail is a very high performance Web-based email system, designed for scaling to large numbers of concurrent users. It takes advantage of the Java Servlet API's memory-resident architecture and multi-threading HTTP response model. It avoids file system accesses through memory caching at every possible point, and never needs to touch the file system at runtime at all if coupled with an IMAP server. It supports POP3, IMAP, and SMTP, including authenticated SMTP. It also provides an extremely sophisticated message rendering system that can easily handle even complex HTML encoded messages with attachments that have been forwarded multiple times.
This is the University of Washington's IMAP source distribution, which includes the IMAP4rev1 server, as well as a POP server that, in addition to offering the normal POP service, can relay commands to an IMAP server, thus permitting existing POP clients to access an IMAP server.
WorldStation is a Java-based control panel to control the Ten-Tec DSP RX-320 shortwave receiver. The RX-320 is a "black box" radio which has no front-panel and is controlled via your PC's serial port. With an appropriate antenna, the RX-320 will allow you to listen to thousands of broadcasts from around the world. WorldStation features integrated Xbase frequency database support and advanced scanning to allow the user to visualize the radio spectrum.
NullLogic Groupware is a modular Web-based groupware and email system designed for contact management and event scheduling. Additional features include private messaging, public discussion forums, webmail, shared bookmarks, file sharing, call tracking, order processing, an XML-RPC API, and integrated POP3 and SMTP servers.
Xamime is a commercial development spawned from Inflex, with various components released back to the OpenSource community (ripMIME, alterMIME, OpenTNEF, ripOLE, and FileType). It provides control of email filtering via spam, virus, email size, file name, file type, file contents, sender and/or receiver name, header defects, and numerous other attributes. It comes with a rapid installation process, a WWW administration interface, interface hooks to external SQL engines, spam filters, virus scanners, and custom scripts.
