JabberTools is a set of tools that help make it easy to use and convert to using Jabber.
The Jabber Web Steward allows users to submit requests for new accounts and allows administrators to allow or deny these requests.
JabberSMTP is a single Perl5 script for bi-directional translation between email and Jabber messages. It acts as a simple MTA and can occupy port 25, although there are ways around that if you don’t have root access. Using JabberSMTP, a Jabber user can receive email messages in any Jabber client, and even create or reply to emails from that Jabber client.
