Manitou-Mail is an open source database-driven mail user-agent and associated utilities. Manitou-Mail project provides a framework and programs for storing, exposing, and managing mail as organized data in a PostgreSQL database. It can be viewed as a versatile alternative to an imap-aware client using imap server storage.
Companies or organizations that use organization-wide mailboxes such as info, support, sales... and need to share the work between the people processing them, monitor and analyze the flow of messages, or even hook their other databases to the messaging system.
Experienced personal users that are willing to put a database at the center of their mail architecture, thus getting powerful retrieval capabilities, extended categorizing of messages, open representation of the mail as structured data.
The user interface runs on Unix/X11 and MS-Windows and is connected to the database, not the mail system. An independant Perl daemon process, controllable by an administrator, is responsible for fetching and sending the mail.
Enhancements:
- This release offers a revamped full text search engine, a new online help system using Qt assistant, modularized Perl code for the mail-database exchanger, along with a number of small bugfixes and enhancements.
- Also, the user interface now compiles on Solaris and BSD-based systems.

Enhancements: Compatible with TB 1.5.0.*

Requirements: Thunderbird 1.0 - 1.5.0.* ALL

Fetch and deliver mail is a simple, lightweight replacement for mail fetching, filtering, and delivery programs such as fetchmail and procmail.
It can fetch using POP3, POP3S, IMAP, IMAPS, or stdin, and deliver to a pipe, file, maildir, mbox, or SMTP server, based on a set of regexps.
Fetch and deliver mail can be used for both single user and multiuser setups, and is designed with privilege separation when running as root.
Enhancements:
- Mostly configuration file enhancements and code cleanup were done since 1.2. ifdef/endif blocks and inline shell commands are allowed in the configuration file.
- A built-in string cache using TDB was added.
- Some extra default tags were added. NNTPS fetching was implemented.
