Did you follow this tutorial to set up the system? http://www.howtoforge.com/perfect_setup_fedora_core_5
What's the output of

uname -m

?

[Andee63]

Yes I did

The output of uname -m is i686

[Andee63]

Ok have fixed the problem with password file. The problem was in my main.cf file not sure what but when I replaced it with the one from the tutorial and then restarted the server it now works. I am now able to send emails out to external servers.
I still have two problems though
1. When I send emails to say another email user on my system I get a loop back error
2. I am unable to receive incoming emails from external sources this may be just a dns error or my isp blocking port 25

[till]

1. When I send emails to say another email user on my system I get a loop back error

Please add the domain / hostname that is mentioned in the loopback error at the end of the file /etc/postfix/local-host-names and restart postfix.

2) This might be solved too when you solve 1).

[Andee63]

Thanks Till
That fixed that problem but I am still unable to receive externally on port 25, will have a word
with my isp.

I do get the error verify=fail in my maillog would that be a problem

[Andee63]

Update:

I have spoken to my isp and they have confirmed they don't block port 25. I have also checked my router and that port 25 is open. Maybe I have some dns or mx setting wrong.

This error has also appeared in my logs

The MX record should be a system name. The system name used should be resolvable with at least an A record.

Try to fix this and try again.
