BlackMail is an Anti-Spam mailer proxy for use with popular MTA's like Sendmail, QMail, and SMail. It is highly configurable, very powerful, very fast, and runs on a large variety of platforms. It has undergone extensive testing, and this is the most stable release, now with Solaris support.
chpp is a general purpose preprocessor. It was designed originally for the purpose of preprocessing HTML code but can be used successfully in other fields of application as well. Highlights are, beside powerful language constructs, CGI-scripting support and an SQL database interface.
Deliver is a program for reliable and flexible local mail delivery. It's a perfect adjunct to your mail transport agent of choice (such as Sendmail or qmail). You can use it to kill spam, drop messages from specific senders, add a [LISTNAME] prefix to the subjects of messages that are delivered through mailing lists, and lots more.
The Download Slave is a very flexible script which is controlled via eMail and stores files requested for downloading on the server's harddisk or sends them via eMail to the user who asked for them. Users are identified by their eMail address and a personal password, so only authorized users can use the service.
DSML is the Directory Services Markup Language, an XML dialect for working with directory information. The DSML Tools provide for the querying of any LDAP directory (with search results output as DSML), the importing of DSML data into any LDAP directory, the directory-context validation of DSML (checking for illegal attributes in the entries, etc.), and the calculation of the differences (for a directory) between two DSML documents to provide an XML Diff algorithm for DSML data. This software makes all LDAP-supporting directories DSML-enabled. It can also check the integrity of DSML data, and show at a glance how two data sets, represented as DSML, differ.
email2sms is a filter written in Perl which converts an e-mail into a form suitable for sending as an SMS message. Its main advantage over the alternatives is that it uses the CPAN module Lingua::EN::Squeeze to compress the text down to as little as 40% of its original size, so you can get much more of your e-mail into the 160 character limit imposed by SMS. It is fully MIME compatible, and has many configurable options, including removal of quoted text. Ideal for use with procmail. A Perl script for sending the output to a typical e-mail to SMS web gateway is included.
