I am using Postfix to send out emails. It works properly when I send email to an external domain, but it does not send the email when I send to the same domain that is configured in Postfix. How do I fix this?
To fix this, do the following:
Add this blank line in your Postfix main.cf file:
mydestination =
Next, reload your Postfix configuration by running:
/etc/init.d/postfix reload
