Hi, I did an NMAP to my new iredmail server. This was the results. I wonder why port 21 is open by default in a new install of iredmail. Can I disable this port and where do I find the config for this?

Nmap scan report for iredmailserver.com
Host is up (0.0097s latency).

Re: Default IPTABLES why port 21

iRedMail stores iptables rules in /etc/default/iptables, port 21 is not open by default.
Could you please check whether you have port 21 defined there?

Not defined... And the output of iptables -L is according to the config file.

Really strange. It's a default install of iredmail with postscreen and manual Certifikatet.

Hm...
