morigin email classifier is a filter that classifies and tags email messages based on the DNS information of the system submitting the mail to your organization.

morigin email classifier can then be used to improve upon existing spam filters such as SpamAssassin.

Open Project Services (OPS) is a project collaboration platform, integrating server components such as e-mail, calendaring, timesheets, documents, knowledge, etc. with standards complient clients. Open Project Services consists of a project server and a set of client extensions.
We are building a project collaboration platform. It consists of a project server that integrates with services needed within a project, e.g. e-mail, calendaring, timesheets, documents, knowledge, etc.
The project server is a Webservices hub based on Java (J2EE). The persistence layer for project information is LDAP. We use OpenLDAP now, but others should also be possible. The e-mail backend makes use of a standard IMAP server. Our reference implementation uses Courier.
We are building extensions/plugins for clients, making them OPS-enabled. We support e.g. Mozilla Thunderbird (XUL) and Squirrelmail (PHP) for e-mail clients. For the calendaring and timesheet components we have a Mozilla Sunbird extension (XUL).
In short: we are building a project collaboration environment on an OSS stack, enriching services with project information, using COTS clients/servers and open standards.
Enhancements:
- This release includes some changes to the underlying LDAP schema to make it possible to disable tasks when they are completed.
- To make use of this new feature, the Web services and the sunbird timesheet client have to be updated.

Twisted Mail project provides client and server implementations of SMTP, POP3, and IMAP4.
These differentiate themselves from the Python standard library implementations both by presenting a much higher-level, easy-to-use interface and in their server components, which allow the implementation of custom servers for each protocol without dealing with protocol-level issues.
Twisted Mail includes a simple demonstration email server which accepts messages over SMTP, stores them in a Maildir arrangement, and can serve them to clients over POP3.
Enhancements:
- The IMAP4 client now properly quotes usernames and passwords when necessary.
- It also handles unsolicited FLAGS responses.
- The IMAP4 server can now parse multiple literals in a single command and to FETCH requests with multiple BODY parts.
- A bug where Deferreds returned from IMAP4 client methods would not receive connection lost notification has been fixed.
- Startup time on OS X has been improved.
- The SMTP server has been sped up.
- The POP3 mailbox API has been expanded to allow Deferreds to be returned in some cases.

MailStore is a tool that is built in python and provides a mail proxy for POP3,IMAP4 and SMTP protocols. However, beyond usual proxies, it makes a backup of all incoming and outgoing email and stores them in a Maildir format.

Emails then can be accessed through an IMAP server run on the same machine using the backup Maildirs as mailboxes.

The idea is to provide a realtime , centralized backup of all incoming and outgoing of an organization without the need of user intervention, especially for organizations that use shared email hosting. Many of this hosting providers allow for only POP3 based access of the email.

Secondly, due to its shared hosting environment , there is limited space hence all email ends up being downloaded directly to the client. Any backup effort has to be taken up by the user on a periodical basis. This is prone to problems due to the fact that users might either forget or a data disaster might happen in between a backup cycle.

With a backup proxy like this all email is always available at the backup proxy. Any backup need be done by the administrator only at the proxy server itself. This we believe to be a much more convenient task then backing up user systems individually.

Secondly the MailStore server will always have all the emails the user has sent or received at any point ,hence the backup will always be current. To access the email, a local IMAP server can be run that will provide the user with access to the email that has been backed up. The user may then add this account to their email client and backup all the email out of it locally. (E.g. In Outlook you would probably export all the email in the account). Following that the user will import back the mail back into its original account.

Thirdly , the system requires minimal administrator involvement. It handles the creation of new maildirs for new domain/user combinations. Hence administrators dont have extra config files to play with whenevr new users are added to the system. Whether a user exists or not is left up to the mailserver that mailStore is proxying.

The mailStore system is built in Python. It has been tested with Python 2.3 and 2.4. Any system which support Python 2.3/ Python 2.4 should be able to run it.
