I installed Fedora Core4, (The Perfect Setup). I'm having problem telneting into localhost 25.

Escape character is '^]'.
220 my.server ESMTP Postfix

I completed the whole setup and was able to send a test message to my gmail email address:
Received: from dpslx.server (dpslx.server [127.0.0.1])
(using TLSv1 with cipher DHE-RSA-AES256-SHA (256/256 bits))
(No client certificate requested)
by virtual.dpslx.server (Postfix) with ESMTP id 658127E4B0

Here's a copy of my netstat -tap:

I think you are allright there:

Escape character is '^]'.
220 my.server ESMTP Postfix

If you see this then you are OK, you have working connection to your postfix smtp server! If you would like to see more of the inner-workings of you server do this: telnet localhost 25

After you have established the connection to your postfix mail server type:

ehlo localhost

But i think you somehow expected something else? I do want to warn you... Make absolutely sure that your server cannot be used by unwanted folks if you plan to connect the server directy to the internet. You can check if you have an open relay at: http://www.abuse.net/relay.html

Well, maybe I'm all right, but not sure! I was able to installed and logged into ISPConfig and everything seems okay, but have not had a chance to play around with it it yet.

Yes, I did telnet localhost 25 and the server hangs and times-out at the:
Escape character is '^]'.
220 my.server ESMTP Postfix

According to the Perfect Setup Tutorial (http://www.howtoforge.com/perfect_setup_fedora_core_4_p4) I'm supposed to connect to the postfix server if everything is okay, but the server is not opening up via telent localhost 25. Funny thing is, I'm able to send email.

When I typed "ehlo localhost" I received command not found.

You must type ehlo localhost when you see the 220 my.server ESMTP Postfix line. That's what zokahn wanted to tell you. :)

Really, if you are just sending a text based test message you should use

helo localhost

the elho command is to indicate that an 8-bit connection is being established. The comanad availabilty does change between methods. If you are new to email - the raw form, once you are connected you can do HELP to get a brief command list.

It doesnt really matter in this case as either will work. After you are connected, nothing else will appear because under normal circumstances an application is doing the connecting and it just starts issuing commands.
