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.
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.
