Postfix with mysql problem

[Snake]

Hello,

I have followed this guide: http://howtoforge.com/virtual-users-...-mysql-fedora8

I have installed the releases but when I trying check the Postfix, Telnet shows:

[root@serv1 log]# telnet localhost 25
Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Connection refused

And dnsstuff shows:

ERROR: I could not complete a connection to any of your mailservers!

correo.domain.tld: Timed out [Last data sent: [Did not connect]]

If this is a timeout problem, note that the DNSreport only waits about 40 seconds for responses, so your mail *may* work fine in this case but you will need to use testing tools specifically designed for such situations to be certain.

Maillog and Message not show anything :S

Can you help me please?

Thanks and regards!
