Why is my IMAP port not showing as open ( yet it works? )
- by Leo
Ive recently setup Postfix and Dovecot IMAP on a Debian Lenny box. Sending to this domain works fine and reading the email via IMAP works fine too. I'm curious though as to why when running nmap, port 10143 is not shown as open.
nmap -sS -O 127.0.0.1
Starting Nmap 4.62 ( http://nmap.org ) at 2011-11-26 21:30 GMT
Interesting ports on localhost.localdomain (127.0.0.1):
Not shown: 1711 closed ports
PORT STATE SERVICE
22/tcp open ssh
25/tcp open smtp
80/tcp open http
3306/tcp open mysql
Am I missing something with NMAP?
Thanks
Leo
