Problem for configuring postfix

Hi,
I installed Fedora Core 1, with graphic Gnome and many of applications it provides at install time.

I also installed postfix.
I was told to stop sendmail, because they do not work together.

I can telnet to port 25 from other computer on my network,
but postfix responds very slow, and it seems there is something wrong with configuration.

What is the simplest configuration I can make to make it run.

Outlook Express just times out, when I try send and recieve.

please hlep.
Is it better to install postfix again? where I can get the installation files?

Thanks

It would be worth adding an entry in /etc/hosts for any connecting pc. The slow response could be due to postfix doing a dns lookup on the connecting client.

How to add other pc
at present I have

127.0.0.1               localhost.localdomain localhost

where  192.168.1.101 is linux itself, and I have other pc on network, as 192.168.1.100, which is an Windows XP. Shall I just add that one like others?

I did telnet like this
telnet 192.168.1.101 25
and I get following line:
220 localhost.localdomain ESMTP Postfix

I entered:
helo localhost

250 localhost.localdomaiin
I entered:

Hi
I guess I am almost there.
I had some configuration issue, header_checks, and that is why it was hanging.

Now I get "Relay access denied", it seems I need to setup some setting in Virtual file.

this is the error I get:
The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was 'navtest@yahoo.com'. Subject 'test', Account: '192.168.1.101', Server: 'www.mydomain.com', Protocol: SMTP, Server Response: '554 <navtest@yahoo.com>: Relay access denied', Port: 25, Secure(SSL): No, Server Error: 554, Error Number: 0x800CCC79

I could not find what i need to type in that file.

Please help

What does your config look like and how are the users based ?
Try checking the "my_networks" line and add the sender's IP there.

I fixed that problem and I can send email, I was giving wrong ip to mynetworks list!
But now the problem is recieving email!
Does postfix act as pop3, or I should install some sort of pop3 too?

for POP3 you should use courier-imap or another IMAP/POP3 daemon.
