Greetings,
My first post to a mailing list, I am sure this is a simple thing that I am overlooking, but even a two week old case with RHEL and I am not hitting on the answer. Please help if you can/want. Situation: Single postfix server and an exchange 2013 server. The company is wanting to keep the same domain across both systems. I am using ldap lookups for virtual domains, this is working great. Internet bound email is also working great. I attempted using an ldap transport lookup keying off a group (the idea is a user not in the group relay to the exchange FE for internal routing). Output of telnet gives me: Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. 220 nmnpfx01.chickasaw.com ESMTP Postfix helo localhost 250 nmnpfx01.chickasaw.com mail from:<postfix-t...@chickasaw.com> 250 2.1.0 Ok rcpt to:<john.ander...@chickasaw.com> 450 4.1.1 <john.ander...@chickasaw.com>: Recipient address rejected: User unknown in virtual mailbox table quit ### postconf -n ### [johnanderson@nmnpfx01 ~]$ 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 fallback_transport = smtp:[relay.chickasaw.com]:25 html_directory = no inet_interfaces = all inet_protocols = ipv4 local_recipient_maps = mail_owner = postfix mailq_path = /usr/bin/mailq.postfix manpage_directory = /usr/share/man mydestination = $myhostname, localhost.$mydomain, localhost myhostname = nmnpfx01.chickasaw.com mynetworks = all newaliases_path = /usr/bin/newaliases.postfix queue_directory = /var/spool/postfix readme_directory = /usr/share/doc/postfix-2.10.1/README_FILES relay_domains = chickasaw.com relayhost = [relay.chickasaw.com] sample_directory = /usr/share/doc/postfix-2.10.1/samples sendmail_path = /usr/sbin/sendmail.postfix setgid_group = postdrop soft_bounce = yes transport_maps = ldap:/etc/postfix/ldap_transport.cf unknown_local_recipient_reject_code = 550 virtual_gid_maps = static:1001 virtual_mailbox_base = /home/vmail/ virtual_mailbox_domains = chickasaw.com virtual_mailbox_maps = ldap:/etc/postfix/ldap-users.cf virtual_uid_maps = static:1001 ### ldap-users.cf ### ## LDAP LOOKUP FILE ## CREATED 4-10-2017 ...omitted result_format = %d/%u/Maildir/ ...omitted ### ### ldap_transport ### ## LDAP Remote Exchange LOOKUP FILE ## CREATED 4-10-2017 ...omitted result_format =%s relay:[relay.chickasaw.com]:25 ...omitted ### postmap here works if the user is NOT a member of the above group. john.ander...@chickasaw.com relay:[relay.chickasaw.com]:25 What we want is for co-existence with exchange, i just dont know what i am missing. I have searched for similar situations and havent found one that had enough detail to help me see what I am missing. Any pointers, tips, or help will be greatly appreciated! Thanks in advance!
