qmail-installer is a shell script that asks the user a few configuration questions, and then downloads, patches, installs, and configures qmail and its dependencies. Currently, the script installs daemontools and ucspi-tcp, and optionally qmailanalog, the SMTP AUTH patch, the qmail-queue patch, and the virus-scan-zip patch. The installer offers a number of modes (outbound only, outbound only with SMTP, normal, and normal with POP). The qmail installation performed by this script is compliant with Dan Bernstein's licensing, and is very close to an LWQ installation.
HamCannon is a Zope/Plone product for managing outbound email marketing. HamCannon is designed for sending ham, not spam: it has much support for helping users unsubscribe and none for hiding from them. HamCannon provides all of the tools required to produce personalized email newsletters or other email marketing, with subscription management, open tracking, bounce tracking and link tracking, complete statistical reporting and complete personalization, limited only by your data.
ezmlm-browse is a Web interface for browsing ezmlm-idx (version 0.40 or later) archives. The presentation is modeled from that of the ezmlm-cgi archive browser that is part of ezmlm-idx, but with several additions. However, the output is completely template-driven, so you can make it fit into your current Web scheme.
Approver is a set of scripts for automatically approving posts to Majordomo-moderated mailing lists based on the sender's email address. Approver also converts HTML email posts to plain text by first filtering them through DEMIME, and it bounces all posts submitted to mailing lists made by non-list members, preventing list moderators from being bombarded by bogus submissions created by email worms and viruses originating from list member's infected computers.
AutoFollowUp (AFU) is a mailing list program meant to run on your Web server. It was created expressly for those users who want to have an autoresponder hosted on their own site, but have severe limitations imposed by the Web server administrator. AutoFollowUp automates the process of following up with your customers. It allows you to create lists of email messages to send. After subscribing, a user could receive a welcome email, and then potentially get another message from you every day, every week, every month, or at any interval you specify.
SmartList is a mailing list manager. It is built on top of procmail and provides for the simple creation and handling of mailing lists, including fully automated subscription/unsubscription/help-request processing, intelligent auto-removal of addresses from the list that cause too many bounces, and a built in archive server (with MIME support).
