Why doesn't adding product to woocommerce cart work?

Question

Mail server

Installed fresh WP and woocommerce. Made the minimum necessary settings. I uploaded demo data, but then I tried it with 1 product. I tried to place a trial order - in Firefox, in Chrome and Edge - the goods do not go into the basket. I click add -, they are added, I go to the basket - "Your basket is empty for now." In WooCommerce" -> "System Status" is all green. There are no caching plugins nginx 1.10 php7, mysql 5.6 Please tell me what to do?

Answer 1

alas, the situation is such that the use of the mail function will almost always lead to the letter getting into spam.
This is due to the use of incorrect headers or the presence of the server's IP address in spam lists.
the simplest solution is to send emails via SMTP. Fortunately, most mail services allow you to "fasten" your domain.
PS. you can look towards the library github.com/PHPMailer/PHPMailer
