Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Ubuntu 12.10)

falko's picture

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, 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. Passwords are stored in encrypted form in the database. In addition to that, this tutorial covers the installation of Amavisd, SpamAssassin and ClamAV so that emails will be scanned for spam and viruses.

falko's picture

This tutorial shows how you can install and run a Question2Answer web site on a Debian Squeeze or Ubuntu 12.10 system that has nginx installed instead of Apache (LEMP = Linux + nginx (pronounced "engine x") + MySQL + PHP). nginx is a HTTP server that uses much less resources than Apache and delivers pages a lot of faster, especially static files. Question2Answer is a free and open source platform for Q&A sites.

Rate Limiting With nginx

falko's picture

This article explains how to use the nginx HttpLimitReqModule to limit the number of requests for a given session. This is useful, for example, if your site is hammered by a bot doing multiple requests per second and thus increasing your server load. With the HttpLimitReqModule you can define a rate limit, and if a visitor exceeds this rate, he will get a 503 error.
