Hi all I am using postfix 2.8 and I have configured two instances of postfix each of them uses different ip and domain . The two instances are running but when I try to send e-mail from one to another I get this error status=deferred (connect to myserver2.com[192.168.1.11]:25: Connection refused)
The configurationm as follows: First Instance (postfix) alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases broken_sasl_auth_clients = yes command_directory = /usr/sbin config_directory = /etc/postfix daemon_directory = /usr/libexec/postfix data_directory = /var/lib/postfix disable_dns_lookups = yes disable_vrfy_command = yes home_mailbox = Maildir/ html_directory = no inet_interfaces = 192.168.56.102,127.0.0.1 local_recipient_maps = proxy:unix:passwd.byname, $alias_maps,$virtual_mailbox_maps local_transport = local mail_owner = postfix mail_spool_directory = /var/spool/mail mailbox_command = /usr/bin/procmail-wrapper -o -a $DOMAIN -d $LOGNAME mailq_path = /usr/bin/mailq manpage_directory = /usr/share/man multi_instance_directories = /etc/postfix-out multi_instance_enable = yes multi_instance_wrapper = ${command_directory}/postmulti -p -- mydestination = localhost mydomain = myserver.com myhostname = mail.mysever.com mynetworks = 192.168.56.0/24, 127.0.0.0/8 myorigin = $mydomain newaliases_path = /usr/bin/newaliases queue_directory = /var/spool/postfix readme_directory = no relay_domains = sample_directory = /etc/postfix sendmail_path = /usr/sbin/sendmail setgid_group = postdrop smtp_bind_address = 192.168.56.102 smtp_host_lookup = native smtpd_banner = $myhostname ESMTP smtpd_sasl_auth_enable = yes smtpd_sasl_path = private/auth smtpd_sasl_security_options = noanonymous smtpd_sasl_type = dovecot transport_maps = hash:/etc/postfix/transport unknown_local_recipient_reject_code = 450 virtual_alias_maps = hash:/etc/postfix/virtual virtual_gid_maps = static:501 virtual_mailbox_base = /home/vmail/ virtual_mailbox_domains = myserver.com,tech-vm.com virtual_mailbox_maps = hash:/etc/postfix/vmailbox virtual_minimum_uid = 500 virtual_transport = virtual virtual_uid_maps = static:501 Second instance (postfix-out) alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases authorized_submit_users = broken_sasl_auth_clients = yes command_directory = /usr/sbin config_directory = /etc/postfix-out/ daemon_directory = /usr/libexec/postfix data_directory = /var/lib/postfix-out debug_peer_level = 2 disable_dns_lookups = yes disable_vrfy_command = yes home_mailbox = Maildir/ html_directory = no inet_interfaces = 192.168.1.11 local_recipient_maps = proxy:unix:passwd.byname, $alias_maps,$virtual_mailbox_maps local_transport = local mail_owner = postfix mail_spool_directory = /var/spool/mail mailbox_command = /usr/bin/procmail-wrapper -o -a $DOMAIN -d $LOGNAME mailq_path = /usr/bin/mailq manpage_directory = /usr/share/man master_service_disable = inet multi_instance_enable = yes multi_instance_name = postfix-out mydestination = localhost mydomain = myserver2.com myhostname = mail.mysever2.com mynetworks = 192.168.1.0/24 myorigin = $mydomain newaliases_path = /usr/bin/newaliases queue_directory = /var/spool/postfix-out readme_directory = no relay_domains = sample_directory = /etc/postfix sendmail_path = /usr/sbin/sendmail setgid_group = postdrop smtp_bind_address = 192.168.1.11 smtp_host_lookup = native smtpd_banner = $myhostname ESMTP smtpd_sasl_auth_enable = yes smtpd_sasl_authenticated_header = yes smtpd_sasl_path = private/auth smtpd_sasl_security_options = noanonymous smtpd_sasl_type = dovecot transport_maps = hash:/etc/postfix-out/transport unknown_local_recipient_reject_code = 550 virtual_alias_maps = hash:/etc/postfix-out/virtual virtual_gid_maps = static:501 virtual_mailbox_base = /home/vmail/ virtual_mailbox_domains = myserver2.com virtual_mailbox_maps = hash:/etc/postfix-out/vmailbox virtual_minimum_uid = 500 virtual_transport = virtual virtual_uid_maps = static:501 regards
