Postfix Virtual Hosting With LDAP Backend & Dovecot (IMAP/POP3) On Ubuntu 8.04

falko — Sun, 03 Aug 2008 12:47:22 +0200

I have been running with a MySQL backend for virtual hosting for some time, but when I discovered Phamm and the added FTP feature I decided to switch to LDAP as backend for Postfix with virtual hosting. In view of the fact that the installation and configuration guide of Phamm is lacking some basic information it took me quite some time to put it all together and get it working. Piecing it all together was not simple so I would like to share how I configured it and got it all working toghether.

Virtual Hosting With Proftpd And MySQL (Incl. Quota) On Ubuntu 8.04 LTS

This document describes how to install a Proftpd server that uses virtual users from a MySQL database instead of real system users. This is much more performant and allows to have thousands of ftp users on a single machine. In addition to that I will show the use of quota with this setup.

Virtual Users And Domains With Postfix, Courier And MySQL (Mandriva 2008.0)

falko — Tue, 15 Jan 2008 11:25:39 +0100

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 will 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 will 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.
