mailq_applet is a GNOME 1 panel applet that shows the status of your outgoing mail queue. It's intended for dialup users who may connect, wait for the queue to drain, then disconnect. Having this on your panel is much more convenient than running mailq over and over again from a terminal. It works with Exim and Sendmail. If you use a different MTA, you may need to make some changes, but the code is so trivial that that shouldn't be difficult. This code is no longer used or maintained by its author.
SmartSign is a set of modules which allow integration of smartcard technology into an OpenCA based Public Key Infrastructure in order to provide smartcard-based digital signature and local authentication security services. It allows direct signing of e-mail and e-news from within Netscape using smartcards and supports signing of generic files from command line. The package includes a PAM module too, which allows system administrators to integrate smartcard-based authentication for local users. A modified version of the OpenSSH client allows secure authentication to a remote server. A couple of command line tools allow signing and verifying generic files from the shell. Finally, a command line interactive shell supports all operations on the card, and can be used to write scripts that automate particular tasks on the card. Currently only Schlumberger Cyberflex Access 16K is supported.
tkbiff allows arbitrary commands to be executed upon mail reception. If you like programs such as xbiff and xbiff++ but wish they were more flexible, then you'll like tkbiff. Unlike other biffs, tkbiff is fully customizable. tkbiff also doesn't waste your valuable screen space with icons; instead, it shows you the mail itself. It supports UNIX, Mac, and Windows, IMAP, POP, and UNIX-style mail files, and SSL and APOP.
VCF2alias is a tool to extract name and email information from VCF attachments (automatically if you use the enclosed mailcap), and writes a line (user-defined) to a file (user-defined). Originally, VCF2alias was aimed at mutt, but it should now work with any mail program that has text-file alias definitions.
XCmail is a MIME and multi POP3 capable mailtool for X11 using the Xclasses X11 layout library. Its main purpose is to read and write mail, allowing any kind of data to be attached. It can handle MIME types, has helpers to show different types, and can encode and decode binary data into ASCII to allow it to be transported as mail over the Internet. It has many built-in functions such as 2 vCards, unlimited POP3 servers, SMTP, SMTP after POP3, SMTP-AUTH (RFC2554), addressbook, encoders, filters, a special spam filter, spell checker, xface, and a new "virtual folder" concept. It also uses external programs to enhance its feature set. XCmail can be extended through a plugin interface.
Maildrop Spam Filter is a Maildrop script file for identifying and adding a header to possible spam. Using the header, suspected spam can be filed in a low-priority mail folder or trashed. All suspected spam is edited to change text/html MIME parts to text/plain so that HTML is not rendered if the message is viewed.
openadaptor is a Java/XML-based software platform which allows for rapid business system integration with little or no custom programming. openadaptor can be loosely classified as EAI (Enterprise Application Integration) software. It is highly extensible and provides many ready-built interface components for JMS, Oracle, Sybase, and TIBCO, as well as data exchange formats such as XML.
