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

Post date: August 3, 2008, 10:08 Category: Installing Views: 4016 Comments
Tutorial quote: 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.
