PerlDAV is a Perl library for modifying content on Web servers using the WebDAV protocol. Now you can LOCK, DELETE, and PUT files, and much more, on a DAV-enabled Web server. The PerlDAV library consists of: HTTP::DAV, an object-oriented Web- DAV client API, dave, the DAV Explorer, an end- user UNIX console program for interacting with WebDAV servers (dave looks and feels like a standard UNIX ftp program).
VK Mail has three main components: an email daemon that acts as a proxy to any standard mail server, an email parser, and a Web mailer. All these together allow users to send email by simply typing an email address in a standard graphical Web browser, and allow better anti-spam control for email recipients. The goal of this project is not to develop an anti-spam email filter that simply deletes the junk messages after they are already delivered to the user. Instead, it rejects emails from spammers.
