Postfix is very picky about who it will except mail for. Make sure your configuration files are setup so it'll recieve mail for your domain. I think by default postfix rejects all non-local mail.
Thanks you too, for the fast reply, i told you what "experts" at postfix maillist told to me, personally i think like you, but all of them told me the same thing.
I post here my postconf results:
alias_database = hash:/etc/postfix/aliases
alias_maps = hash:/etc/postfix/aliases
command_directory = /usr/sbin
config_directory = /etc/postfix
daemon_directory = /usr/lib/postfix
debug_peer_level = 2
default_privs = nobody
delay_warning_time = 4
inet_interfaces = all
mail_owner = postfix
mail_spool_directory = /var/spool/mail
mailq_path = /usr/bin/mailq.postfix
manpage_directory = /usr/share/man
mydomain = estudioviegas.com.ar
myhostname = estudioviegas.com.ar
mynetworks = 127.0.0.0/8, 184.108.40.206/24
myorigin = $mydomain
queue_directory = /var/spool/postfix
readme_directory = /usr/share/doc/postfix-2.0.13/README_FILES
relayhost = smtp.ciudad.com.ar
sample_directory = /usr/share/doc/postfix-2.0.13/samples
setgid_group = postdrop
smtpd_banner = $myhostname ESMTP $mail_name
unknown_local_recipient_reject_code = 450
Hope this helps!!
