Wordpress and Postfix issues not receving emails that are sent to email addresses that are on the site domain.

LEMP Email Nginx WordPress

I have a multisite setup running on lempstack w ubuntu4.11. Installed postfix and have no problem sending emails to my personal email address or other member addresses. But when a notification is sent out or I send an email to an address that is on the site domain (Like the example below) its not received, says its sent but it never comes through.
wpsite.com support@wpsite.com
Any Ideas?

This is because Postfix assumed the hostname for itself handles the mail for that hostname. To fix this edit your postfix's main.cf and add a line like this:

mydestination =

If you already have this line and it has a bunch of domains, make sure the hostname you are having issues with isn't on the list.

Then reload postfix with

/etc/init.d/postfix reload
