TWIG is a Web-based groupware suite written in PHP, compatible with both PHP3 and PHP4. Its features include IMAP and POP3 email, Usenet newsgroups, contact management, scheduling, shared notes and bookmarks, a todo list, and meeting announcements. Any piece of information can be shared with others via group oriented access controls. By using only plain HTML, it is a simple, cross-platform, fast, and browser-independent way to access or share almost any kind of information, without the complexity or costs of other intranet/groupware packages. It is fully internationalized, with 24 translations.
MyPhPim contains a Web-based email client, todo list, notes app, addressbook, and calendar. Future goals include features for Palm Pilot syncing and file storage. MyPhPim is multi-user, so you can share your records with other users and/or other groups. Multiple mailboxes for each user can be defined. MyPhPim requires MySQL, and PHP4 with IMAP, MySQL, mcrypt, and socket support.
kmMail is a PHP-based mail program, based on the mail functionality of Keftamail and is being developed by current Kefta employees. It is meant to be a framework for putting a web-based mail program on your site, but is still robust enough to drop into your current site with little to no modification. The goals of kmMail are MIME compliance, speed, low overhead, and an enjoyable user interface.
Replex is an administrative tool for managing email on any Unix-like OS. It can handle multiple domains, users, mailing lists, etc. without requiring creation of Unix user accounts for mailboxes or authentication. Replex is written in PHP4 and stores all information in a MySQL database. Replex relies on Postfix for SMTP and Cyrus for IMAP and POP3 accounts.
POP 3 client is a PHP class that allows you to access mail boxes using the POP3 protocol. It provides a stream wrapper class for retrieving messages like files using the PHP fopen function, establishes secure connections using TLS, accesses servers using normal and APOP login methods, supports authentication mechanisms such as PLAIN, LOGIN, CRAM-MD5, NTLM (Windows or Linux/Unix via Samba) via the PHP SASL library, and supports listing of message sizes, retrieval of a message at once, separating the headers from the body, retrieving a message in small chunks to not exceed the available memory, and deleting messages.
Twiggi Web Based Groupware is a Web based groupware application, written in PHP4, using MySQL as its database engine. It was originally based on the excellent TWIG project. With many on-going enhancements, it is similar to Microsoft Outlook, and features the following modules: twiggi today, Mail, Contacts, Notes, ToDo, Bookmarks, and extensive online help (available in English and German). Twiggi has full language support for German, Dutch, Italian, and English.
eXtended Account Management System (XAMS) allows Administration of Unix, Web, FTP, DNS, and email accounts to manage a provider's typical userbase. Especially focusing on email account management, it enables you to easily create accounts, set aliases, and delegate domain administration to 2nd party resellers or customers. It uses PHP with MySQL or PostgreSQL as a backend, and is therefore able to manage tons of email accounts independently from your Unix/Linux accounts. Exim for SMTP and Courier for POP/IMAP are fully supported, but postfix, Cyrus, and qmail can be used too.
