Default URGENT PLEASE: 3rd Time Installing and Still Have SMTP Issues with PostFix

Hello There,

I need some help with my SMTP settings. I followed this tutorial to the 't':

http://www.howtoforge.com/perfect-se...64-ispconfig-3

First the problem.

I cannot connect to my SMTP externally from my server. If a telnet on the server I get a response but when I telnet on a separate machine I get "Unable to connect to remote host". After trying telnet I tried added my account to an email client with password authentication and still unable to connect.

Here is some output information:

postconf -a
