Install and configure and secure a Mail server on a Centos 6 VPS (or other if you like).
The server have to support IDN mail addresses containing non ASCII chars in both local and domain parts such as: اسم.نسب@مجال.شبكة
In your proposal please respond to these questions:
1. Have you ever installed or configured a mail server?
2. What are the main software packages will you use in this project?
3. For the domain part it's punnycode, but for the local part how will you activate UTF8 support?
