Delete Qmail Server messages Queue

Post date: January 12, 2007, 18:01 Category: Software Views: 3463 Comments
Tutorial quote: qmail is a mail transfer agent that runs on Unix. It was more secure replacement for the popular Sendmail program. The author offered a $500 prize for the first person to publish a verifiable security hole in the latest version of the software.

This is a useful thing to do in a number of situations. For instance, if you are hit with a spamming attack, you can temporarily instate a second Qmail installation (once the spam run is finished), allow it to take over mail receipt,and then use this tool to clean the offending mails out of the queue before switching over to the main Qmail installation once again.

Virtual Users & Domains With Postfix, Courier, MySQL, SquirrelMail (Fedora 10)

Post date: February 1, 2009, 11:02 Category: Installing Views: 4708 Comments
Tutorial quote: This document describes how to install a Postfix mail server that is based on virtual users and domains, i.e. users and domains that are in a MySQL database. I'll also demonstrate the installation and configuration of Courier (Courier-POP3, Courier-IMAP), so that Courier can authenticate against the same MySQL database Postfix uses. The resulting Postfix server is capable of SMTP-AUTH and TLS and quota (quota is not built into Postfix by default, I'll show how to patch your Postfix appropriately). Passwords are stored in encrypted form in the database (most documents I found were dealing with plain text passwords which is a security risk). In addition to that, this tutorial covers the installation of Amavisd, SpamAssassin and ClamAV so that emails will be scanned for spam and viruses. I will also show how to install SquirrelMail as a webmail interface so that users can read and send emails and change their passwords.
