Getting "Connection Refused" when trying to connect through port 143

Posted on 2009-07-06
Last Modified: 2013-12-06
I have setup a Postfix server and can send and recieve mail using the webadmin interface.
Whenever I try to connect to port 143  with either fsocketopen in a php script, or telnet I get a "Connection refused" error.

Iptables has nothing set up.
hosts.deny has "portmap: ALL EXCEPT"

Any advice regarding troubleshooting this would be greatly appreciated!

are you behind a firewall?  Is the port blocked or busy?

I am running the script from the same server, and using telnet from the server also.
(As there is nothing in iptables, I presume there is effectively no firewall.)
What method should I use to tell if the port is blocked or busy?

Port 143 has nothing to do with Postfix.

Are you running a POP/IMAP server and has the configuration file been updated to do IMAP?
