Due to the popularity of Gmail, Google Apps, Outlook.com, Yahoo! Mail & a myriad of other providers, many cloud-server users mistakenly fail to install a mail server, initially. However, humans are not the only ones that send electronic mail. If fact, many Linux server applications also need to send email. This tutorial will review how to install a send-only mail server on Ubuntu 12.04.
It works! thank you very much :)
