Hi. I've set up postfix and I've followed this guide: https://www.digitalocean.com/community/articles/how-to-set-up-a-postfix-e-mail-server-with-dovecot I'm running an Ubuntu droplet. I'm trying to get my mail working for my website so that I can send and receive mails. I have managed to set up so I can send mails. But I can't figure out how I will go about receiving mails?? I have checked my /var/mail/ folder but there's nothing there except a file called root. What have I missed here?
