Not receiving mails from droplet - cPanel points to Droplet

Question

Hello guys,

I have a domain hosted on a cPanel account (not in Digital Ocean) and I have a Magento running on a Droplet Ubuntu LAMP 14.04.

The problem is all my emails account are hosted by cPanel and the notification emails from Magento do not arrive to my emails.

How ever, if I set any other email the droplet does deliver the message. It seems the internal emails are getting lock inside the droplet.

Thanks @kamaln7 I notice that the server is using exim instead of sendmail.

I tested this: exim -bt me@mydomain.com

The result was: R: system_aliases for me@mydomain.com me@mydomain.com is undeliverable: Unrouteable address

Hi!

If you’re running sendmail, it might be trying to deliver the emails internally. Another user had the same issue, see this answer for a solution.

If you’re running postfix, try adding the following lines to /etc/postfix/main.cf (at the very bottom of the file):

mydestination = localhost.localdomain, localhost
fallback_transport = relay

Make sure you restart postfix so that the changes take effect:

sudo service postfix restart
