Wordpress is not sending emails
Hello, I need some directions, please. I have a web server successfully running on Ubuntu 14.04. LAMP is properly configured. Everything works flawless. Recently, I decided to try Wordpress. I manually installed Wordpress 5.0.3. Everything is working just fine, except for the fact that I tryed to change the admin e-mail in Wordpress and it says I'll receive a confirmation e-mail, which never arrives. I'm confused. I have no mail server. What is happening exactly and what are the next steps I should take?
