Linux Mail Server: Exim4

Whispers Mail Server

Stack

• Web server (Apache)
• Database server (MySQL)
• Email server (MTA) (Exim4)
• IMAP server (Dovecot)
• Webmail server (Roundcube)

Install

• apt-get install apache2-mpm-prefork
  • (Some of these email servers require PHP; PHP is crappy and requires mpm-prefork (the ‘slow’ version of Apache))
• apt-get install mysql-client
  • (should auto-install something like: mysql-common + mysql-client-5.5)
• apt-get install mysql-server
  • (should auto-install something like: mysql-server-5.5 + mysql-server-core-5.5)
• apt-get install exim4
• apt-get install exim4-base
• apt-get install exim4-config
• apt-get install exim4-daemon-heavy
  • (there’s an “exim4-mysql” that might be sufficient to replace this, but I gave up: there are way too many exim4 packages, and no help for installing the “correct” set, so … just pick this and get the lot!)
• apt-get install dovecot-core
• apt-get install dovecot-imapd
• apt-get install dovecot-mysql
• apt-get install roundcube
• apt-get install roundcube-core
• apt-get install roundcube-mysql

Setup

DNS

You should know about this already: you need an “MX” record on your DNS server, and it needs to point to your main server where you’ll run your email, web, etc.
