Problemas en Maillog de Postfix

[vempire]

hola...disculpen mi demora.

el resultado del postconf -n es el siguiente:

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

mailq_path = /usr/bin/mailq.postfix
manpage_directory = /usr/share/man
maps_rbl_domains = relays.ordb.org list.dsbl.org blackholes.mail-abuse.org dialups.mail-abuse.org relays.mail-abuse.org
mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain
mydomain = microexpertos.cl

unknown_local_recipient_reject_code = 550
virtual_alias_maps = mysql:/etc/postfix/mysql_virtual_alias_maps.cf
virtual_gid_maps = static:1001
virtual_mailbox_base = /usr/local/virtual
virtual_mailbox_domains = mysql:/etc/postfix/mysql_virtual_domains_maps.cf
virtual_mailbox_limit = 51200000
virtual_mailbox_maps = mysql:/etc/postfix/mysql_virtual_mailbox_maps.cf
