PostFix send emails as domain.localdomain instead of domain.org
So, I,ve setup up postfix in my server following this article https://www.digitalocean.com/community/tutorials/how-to-install-and-configure-postfix-as-a-send-only-smtp-server-on-ubuntu-16-04. Whe i make the indicated test of the article mails are reviced as email@example.com instead of the desire @innovaclub.org. I uncommented the myorigin = /etc/mailname line and edited the mailname file adding innovaclub.org in the firstline but still not working. Any help will be much appreciatte.
