POP3 & IMAP Server Installation  
with SQL Authentication, Using Postfix, Dovecot & MySQL

This tutorial shows an installation of Dovecot & Postfix with MySQL authentication.  The emails and domains are all virtual and are configured authenticating to a MySQL backend.  It also allows multiple emails and multiple domains to all be the same virtual user. ie: me@mydomain, you@mydomain, me@someotherdomain can all be accessed via the same account (or any of the accounts, if you'd like). The installation will include the packages required for both IMAP and POP3 connections, but the POP3 will not be enabled in the configuration...

ProFTPd Install  

with TLS and MySQL authentication

Using ProFTPd and its SQL module for MySQL, it is possible to give FTP access to non system users. By doing so, one can give access to a Virtual User which is only allowed to use the FTP service. FTP is a very insecure protocol because all passwords and all data are transferred in clear text. By using TLS, the whole communication can be encrypted, thus making FTP much more secure.

This Tutorial will show how to create and populate the user and group tables as well as configure proftpd in order to use the MySQL backend.
