Email not working with fresh Drupal install on Ubuntu 14.04
I created a Droplet using Ubuntu 14.04 and the 1-click Drupal Image. The image creates the server with Nginx, php-fm, and MySQL along with the latest version of Drupal (currently 7.32). Everything went well but I noticed soon after that Drupal cannot send emails. When I try to create a test user Drupal displays the following alert:
Unable to send e-mail. Contact the site administrator if the problem persists.
Can Ubuntu or PHP send mail for Drupal or do I need to set up a mail transfer agent like Sendmail or Postfix?
