STEEMIT registration ( ERROR : mail: to <********>, from <null>, template confirm_email (not sent due to not production env)
I have installed site steemit and mining on my own server.
When I running the site steemit on Ubuntu 16 , its starts ok, .
and when I trying to registering a new user, in the www.my-steemit-site.com , I will not receive the confirmation in my email box.
In the console I see the logs:
mail: to user@email, from null, template confirm_email (not sent due to not production env)
--
How I can I add the production env and what is the value of this?
