How to setup postfix to send email not as spam?
I create a WordPress droplet with ubuntu 14.04 and install postfix, it can send mail to the user when user register, but the mail client(Gmail) always treats the mail as SPAM, and I found that the send from is “firstname.lastname@example.org”.
How to setup the send from correctly in postfix so that the mail client doesn’t treat the mail that my server sent as SPAM.
