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.
The modular syslog allows for an easy implementation of input and output modules. The modules that mantain compatibility with its precursor are included in the standard distribution along with four modules: om_peo (an implementation of PEO-1 and L-PEO, two algorithmic protocols for integrity checking), om_mysql and om_pgsql (modules that sends output to a mysql and postgresql database, respectively) and om_regex (a module that allows output redirection using regular expressions).
The TenDRA compiler is a C/C++ compiler aimed at being a state of the art compiler: incorporating new research ideas, always producing correct code, and improving compiler performance where possible given the previous points. It offers ANSI/ISO C features and strong code verification. It is developed on a number of different operating systems and architectures.
Net::FTPServer is a full-featured, secure, extensible, and highly configurable FTP server which can serve files from a standard file system or a relational database. It is written in Perl, which provides natural protection against buffer overflows. It has feature parity with popular C-based servers such as wu-ftpd. The server offers virtual hosts (IP-based and experimental IP-less). It is configurable in Perl, for both small Perl "hacks" in the configuration file all the way up to complete server "personalities". It supports the latest RFCs and Internet Drafts. Authentication may be done through /etc/passwd, PAM or an authentication plug-in. Resource limits are supported. The server may run standalone or from inetd. chroot() jails are supported along with sophisticated programmable access control rules. All aspects of server use and configuration are comprehensively documented in a manual running to some 50 pages.
