Email not working with fresh Drupal install on Ubuntu 14.04

Posted October 17, 2014 12.4k views

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?

  • Yes - you have two options, using the SMTP module for Drupal and configuring Postfix to allow connections from localhost. Or easier - update the permission on /etc/mailname which you’ll find now only is readable for root. It’s safe to allow change that to 644.

In order to send emails from your droplet, you’ll need to have an MTA installed such as Postfix. You can install it by running:

sudo apt-get install postfix

Then, edit /etc/postfix/ and set inet_interfaces to loopback-only:

inet_interfaces = loopback-only

Finally, restart postfix:

sudo service postfix restart
