Multidomains Postfix - Dovecot - RoundeCube Setup

Dear Bidders, The project consists on: 1. Installing Postfix - Dovecot and RoundCube on the same Ubuntu Server. 2. The server will host many domains the setup should support aliases, catch all and emails on each domain 3. hosted on the server. 4. The server does not run Appache but runs Nginx Web Server. 5. We not use any Postfix WebBased Interface. Virtual domains and aliases are created on the server. 6. You'll have a root access to the server like you can setup all the required stuff without security limitations. 7. Emails are rooted to real Linux users : ex. root user. 8. The RounCube solution should run on Nginx. You can use the default setup of nginx for your job. We will define later a sub-domain ( ex. [login to view URL] ) 9. The suggested solution should support : 9.1 Redirection an email to an external email ( ex. gmail ) with keeping a copy locally. 9.2 Creating a catch all on a domain 9.3. Redirection all a server domain emails to another server domain ( same server ) To deliver : A. Shell script that can install the all the necessary components on a clean server. Please note that : N1. if you are not able to create a script that does all the job, we can accept the alternative of a .doc file to explain all the setup process to configure a full working Email Server. But we prefer a .sh that does all the job for once. N2. If you need a Webmin installed on the server for editing the Postfix and Dovecot configuration files easilly : You can install it. No problem about that. N3. We are looking for just serious bidders and people who can deliver the project with less maintenance and setup hassle.
