Problemas en Maillog de Postfix

[vempire]

hola

este es el postconf -n

alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases
command_directory = /usr/sbin
config_directory = /etc/postfix
content_filter = smtp-amavis:[127.0.0.1]:10024
daemon_directory = /usr/libexec/postfix
debug_peer_level = 2
header_checks = regexp:/etc/postfix/header_checks
html_directory = no
mail_owner = postfix
mail_spool_directory = /var/spool/mail
mailq_path = /usr/bin/mailq.postfix
manpage_directory = /usr/share/man
mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain
mydomain = microexpertos.cl
myhostname = sputnik.microexpertos.cl
mynetworks = 172.30.10.0/24, 127.0.0.0/8
myorigin = $mydomain
newaliases_path = /usr/bin/newaliases.postfix
queue_directory = /var/spool/postfix
readme_directory = /usr/share/doc/postfix-2.2.10/README_FILES
relayhost = 172.30.10.4
sample_directory = /usr/share/doc/postfix-2.2.10/samples
sendmail_path = /usr/sbin/sendmail.postfix
setgid_group = postdrop
unknown_local_recipient_reject_code = 550

hice lo que me pediste, desinstale postfix y lo instale con el contosplus

funciona todo ok salvo porque me bloquea dominios de correos q no debiese bloquear.
la idea de esta maquina, es que sea un relayhost.
