[solved]Postfix connection timeout sending with SMTP

[inertia]

When I send mails from the SMTP they are not reaching the destination.

Code:

EAF363501720      599 Thu Aug  2 08:00:57  mail.xx.xx
               (connect to hotmail.com[65.55.72.151]:25: Connection timed out)

It's happening regardless of where I send mail to (except locally).

Seems it was a reverse dns problem, I have fixed it now.
