+Mail-in-a-Box provides a single shell script that turns a fresh Ubuntu 14.04 LTS 64-bit machine into a working mail server, including:
 
 * An SMTP server for sending/receiving mail, with STARTTLS required for authentication, and greylisting to cut down on spam (postfix, postgrey).
 * An IMAP server for checking your mail, with SSL required (dovecot).
 * A webmail client over SSL so you can check your email from a web browser (roundcube, nginx).
 * Spam filtering with spam automatically going to your Spam folder (spamassassin).
 * DKIM signing on outgoing messages (opendkim).
-* The machine acts as its own DNS server and is automatically configured for SPF and DKIM (nsd3).
+* The machine acts as its own DNS server and is automatically configured for SPF and DKIM (nsd).
 * Configuration of mailboxes and mail aliases is done using a command-line tool.
 * Basic system services like a firewall, intrusion protection, and setting the system clock are automatically configured (ufw, fail2ban, ntp).

 Get a Server
 ------------
 
-* Get a server. I've been a long-time customer of Rimuhosting.com which provides cheap VPS machines at several locations around the world. You could also go with Linode.com or any other cloud or VPS (virtual server) provider. (If you want to test on Amazon EC2, I've got instructions for you in ec2/README.md.) In a cloud environment like EC2 where your server's IP address is dynamic, this is a good time to assign a static IP (like a EC2 Elastic IP).

Don't use Amazon Web Services though: Many of their IP addresses have a bad reputation because they've been used to send spam.
 
-* Choose Ubuntu 13.04 amd64 as your operating system (aka a Linux distribution). You won't need much memory or disk space. 768 MB of memory (RAM) and 4G of disk space should be plenty.

 * Once the machine is running, set up Reverse DNS. Each ISP handles that differently. You'll have to figure out from your ISP how to do that. Set the reverse DNS to the hostname you chose above (in my case `box.occams.info`).
