Dear all, My question is a bit of general one. Sorry for off topic if any. I would highly appreciate any feedback or URLs for further reading. I'm planning to migrate my mail server from iPlanet Messaging Server (which includes iPlanet Directory Server) to qmail-ldap.
Here is my setup: I have two domains: first one is a corporative domain - domain1.org. iPlanet Messaging Server is responsible for this domain - there is a central LDAP server placed at headquarters configured for daily synchronization with our LDAP server which consists of local domain1.org users. If someone from outside sends a message to [EMAIL PROTECTED] the message passes through headquarters iPlanet Messaging Server then goes to our iPlanet Messaging Server which finally checks a user through LDAP and forwards email to the internal mail server (through LDAP's alias record). domain1.org mail server is configured to accept mail _only_ from the headquarters' mail server. Second domain is a regular one with no LDAP authorization - domain2.org, resides on internal mail server powered by sendmail and configured to accept mail from anywhere. This is the place where users are authenticated, so if someone sends a message either to [EMAIL PROTECTED] or [EMAIL PROTECTED] the message will end up at this server. The question is - is it possible to simulate the same behavior with qmail-ldap? I'm planning to setup external qmail-ldap mail server configured to accept both domain1.org and domain2.org mail messages (with antivirus/antispam protection) and forward all emails to the internal server. So, as far as I understood, I have to install OpenLDAP + qmail-ldap on the external server, update OpenLDAP server with my scheme, but should I have two instances of qmail running? I think about two network interfaces - one NIC will be responsible for domain1.org, another one for domain2.org - both should simply forward all incoming emails to the internal mail server. Is it possible to have such system working? I would really appreciate any suggestions or comments! Thank you in advance! Roman
