SMTP Failed 250

Hi all,

H was able to receive and sending email when my site is only 1, yet when the new sites (with email) being added, my first email cannot be sent again.

Here was my postconf -n result; [root@NATA-KVM-SSD-IIX3 ~]# postconf -n alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases command_directory = /usr/sbin config_directory = /etc/postfix daemon_directory = /usr/libexec/postfix data_directory = /var/lib/postfix debug_peer_level = 2 debugger_command = PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin ddd $daemon_directory/$process_name $process_id & sleep 5 html_directory = no inet_interfaces = localhost inet_protocols = all mailq_path = /usr/bin/mailq.postfix manpage_directory = /usr/share/man myorigin = $mydomain newaliases_path = /usr/bin/newaliases.postfix readme_directory = /usr/share/doc/postfix-2.10.1/README_FILES sample_directory = /usr/share/doc/postfix-2.10.1/samples sendmail_path = /usr/sbin/sendmail.postfix setgid_group = postdrop smtp_use_tls = yes smtpd_recipient_restrictions = permit_sasl_authenticated smtpd_relay_restrictions = permit_sasl_authenticated defer_unauth_destination unknown_local_recipient_reject_code = 550

My postfix vesion 2.10.1
