Server not receiving mail

[speedstic]

Hello All,

I've been trying to setup an email server (postfix, cyrus-sasl, mysql) for sometime now and I think i'm getting close.
However, when i try to send an email to my domain, it doesn't arrive.
But then i try to telnet in to the server and send an email that way and it works.
I've telnet'd from inside and outside my network.
From the /var/log/messages, I can't even see that mail reaches the server and is rejected,
How can I check where the problem lies?
Any help would be appreciated.

If it helps, here is my main.cf:

After 1 day i received a message saying the server is not responding.

I telnet in using my PPC and 1XEV-DO connection to mail.sproon.com port 25, I did the:
mail from:<a@a.com>
rctp to:<adam@sproon.com>
commands as well as the ehlo and helo commands, all work just fine.

I don't have a /var/log/maillog, i didn't explicitly specify logging in main.cf

My router has port 25 forwarded to the right PC.
I use this PC as a web server as well and my /etc/hosts looks like this.

127.0.0.1 web.sproon.com web mail.sproon.com mail localhost.localdomain localhost

Could this be the cause of the problem?

Hello speedstic,

First of all for some mail to reach your mail server for the domain proon.com you have to have an MX record in the DNS of your domain pointing to the real (internet) mail server's address. This means that when I do

[speedstic]

I have an MX record.
I can also access the server via telnet on port 25 from outside the network.
and use smtp commands.
using dnsreport.com, it appears that everything is fine,
unfortunately for me it isn't

Sort out your syslog so you can see what Postfix is doing.
