ok, so for clarify a little more for me. with this config the mail arrive to the zimbra, but... now the zimbra mails dosent go to any other side.
broken_sasl_auth_clients = yes 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 = all inet_protocols = all mail_owner = postfix mailq_path = /usr/bin/mailq.postfix manpage_directory = /usr/share/man mydomain = mydomain.org.ar myhostname = postfix.mydomain.org.ar myorigin = $mydomain newaliases_path = /usr/bin/newaliases.postfix queue_directory = /var/spool/postfix readme_directory = /usr/share/doc/postfix-2.10.1/README_FILES relay_domains = mydomain.org.ar relayhost = email.$mydomain sample_directory = /usr/share/doc/postfix-2.10.1/samples sendmail_path = /usr/sbin/sendmail.postfix setgid_group = postdrop smtpd_banner = $myhostname ESMTP $mail_name ($mail_version) smtpd_recipient_restrictions = permit_mynetworks,permit_sasl_authenticated,reject_unauth_destination smtpd_sasl_auth_enable = yes smtpd_sasl_local_domain = mydomain.org.ar smtpd_sasl_path = /etc/sasl2/smtpd.conf smtpd_sasl_security_options = noanonymous unknown_local_recipient_reject_code = 550 The mail arrive because this "relayhost = email.$mydomain"... but does is not good i think, not just for the error, is also because now when i want to send a mail from zimbra to other side, zimbra pass that mail to postfix and postfix give tha mail back to zimbra... i think. im wright?? Thanks, im gonna try the transport command. -- Sent from: http://postfix.1071664.n5.nabble.com/Postfix-Users-f2.html
