My setup works, I just need to find if it's really a correct configuration. The issue: I don't have the machine with the organization's domain as MX for my domain. Mails are "[EMAIL PROTECTED]" and the MX is machinexyz.organization.tld. I want mails to "anyone" in the aliases file to be sent correctly (either to another account on my organization's domain or an outside email address). Please read the next part of my email to understand.
Scenario: I'm running postfix-2.3.2-28. I have a machine which acts as both MX and smtp-out for other machine, the machine with my organization's mail domain. I use LDAP for the user lookup tables. Everything works ok, I guess config makes sense (I'm reading http://www.postfix.org/postconf.5.html). On the MX machine, I don't run the IMAP server, it's also on a separate machine, and there I run another postfix. "Organization's domain" = city.organization.tld (there are no other *.organization.tld, city = the whole organization) MX machine = machinexyz.organization.tld IMAP machine = machinexyz2.organization.tld INTERNET --"(a)"--> MX_MACHINE --"(b)"--> IMAP_MACHINE (a) mail to [EMAIL PROTECTED] arrives (a) Still on "a" MX machine finds user because he is looked up on LDAP (relay_recipient_maps) (b) Message is delivered using transport "city.organization.tld relay [xx.xx.xx.xx]" where xx.xx.xx.xx is the ip address of the final machine, running IMAP/postfix. There I use Dovecot LDA as transport. So, to be clear, I want to have aliases for city.organization.tld, either to another account on city.organization.tld or to [EMAIL PROTECTED], for instance to be correctly processed by: the first machine which sees the message (mx machine) and the final machine, the imap machine (there I run postfix, as I said). ------------ MX MACHINE -- MX MACHINE alias_maps = hash:/etc/aliases, ldap:ldaplocal, ldap:/etc/postfix/ldap-local.cf local_recipient_maps = hash:/etc/aliases, ldap:ldaplocal, ldap:/etc/postfix/ldap-local.cf virtual_alias_maps = hash:/etc/postfix/virtual virtual_alias_domains = hash:/etc/postfix/virtual virtual_maps = ldap:/etc/postfix/ldap-local.cf relay_recipient_maps = ldap:ldaplocal, ldap:/etc/postfix/ldap-local.cf ldaplocal_server_host=ldapserver.organization.tld ldaplocal_search_base=ou=people,dc=organization,dc=tld ldaplocal_query_filter=(&(|(&(objectclass=postfixuser (objectclass=inetlocalmailrecipient)) (objectclass=groupofuniquenames) (mail=%s)) ldaplocal_result_attribute=mailRoutingAddress transport_maps = hash:/etc/postfix/transport content_filter=smtp-amavis:[127.0.0.1]:10024 mydestination = $myhostname, localhost.$mydomain relay_domains = city.organization.tld ("organization's domain") smtpd_recipient_restrictions = permit_mynetworks, permit_auth_destination, reject_unauth_destination, reject_unverified_recipient, check_recipient_access unverified_recipient_reject_code = 559 mynetworks = 127.0.0.0/8, xx.xx.0.0/16 unknown_local_recipient_reject_code = 450 myhostname = machinexyz.organization.tld (mx machine) ------------ MX MACHINE -- MX MACHINE ------------ MX MACHINE TRANSPORT city.organization.tld relay:[xx.xx.xx.xx] where xx.xx.xx.xx is the ip address with IMAP server ------------ MX MACHINE TRANSPORT IMAP/"FINAL DESTINATION" MACHINE MAIN.CF: Exact the same present on mx machine, except for: mydestination = $myhostname, localhost.$mydomain, city.organization.tld dovecot_destination_recipient_limit = 1 mailbox_transport = dovecot mydestination = $myhostname, localhost.$mydomain, city.organization.tld Solution A) Should I configure mx machine to have the city.organization.tld domain as destination? That way /etc/aliases would be read, as of now, I think the mx machine looks first and only on the relay_recipient table which is LDAP. Solution B) (THIS IS WORKING) I add the desired alias to both "mx machine" /etc/aliases, and "imap machine" /etc/aliases... Does that make sense, is it a correct configuration? Or just a wrong configuration which happens to work, but is not really correct? = internet banking Open A Bank Account Online.
