I have a fresh Ubuntu 16.04 server and I have to create mail server on it. I followed this tutorial that uses postfix & dovecot. Now I am able to sent email from server using mail
command to my personal email but Thunderbird fails to connect and configure my created email. Email related processes seems working:
tcp 0 0 0.0.0.0:25 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:993 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:995 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:110 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:143 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN
It could be because of my DNS entries. I'm not expert at these concepts. If you can help me, I'll appreciate it a lot.
P.S. ufw
