thank and hope for helping hands

anyone? please help. thanks

do u have a firewall installed? my guess is that firewall is blocking packets from/to port 25.
what errors do you see in the maillog if there's any and what error do you receive from sending mail from the internet? was it bounced?


::edit::

oopps!! there is something wrong with your configuration. your mydestination line is i gez at fault.. try adding example.com to your mydestination line and test it.. or if you want to keep it dat way try sending mail from the internet to user@mail.example.com and postfix will accept it.
