Port problem setting up e-mail server
I've set up my e-mail server using this tutorial: www.digitalocean.com/... (without using SSL)
Everything seems to be working, all the services are started.
I've opened the correct ports using UFW:
To Action From -- ------ ---- OpenSSH ALLOW Anywhere Apache Full ALLOW Anywhere Dovecot IMAP ALLOW Anywhere Dovecot POP3 ALLOW Anywhere Postfix ALLOW Anywhere OpenSSH (v6) ALLOW Anywhere (v6) Apache Full (v6) ALLOW Anywhere (v6) Dovecot IMAP (v6) ALLOW Anywhere (v6) Dovecot POP3 (v6) ALLOW Anywhere (v6) Postfix (v6) ALLOW Anywhere (v6)
When I do a port scan this is the result:
PORT STATE SERVICE 22/tcp open ssh 25/tcp open smtp 80/tcp open http 110/tcp closed pop3 143/tcp closed imap 443/tcp closed https
How is it that the IMAP and POP3 ports are closed? I cannot connect to it from any client.
