Hi all, I'm planning now a LDAP-based Postfix setup and struggling designing the how the LDAP schema should look like.
Basically the schema should : - Be OpenLDAP compatible - Allow multidomain - Host transports for each defined account / email address. - Integrate with dovecot and/or cyrus-imapd. The goal is to produce a scalable, HA system based on RHEL5 stock components. The solution would look something like : - 2x Internet-facing antispam appliances (Ironport, Barracuda, whatever) - 2x Postfix "mailhub" servers. They receive emails from appliances and route the mail internally based on transport rules to the right "mailbox" server. Also host outgoing email queues and do relay for SASL-authenticated users. - 2 to n "mailbox" servers running IMAP server (perhaps with LMTP capabilities) and Postfix if necessary for mail storage. Anybody has a similar setup and is willing to share? :-) Thanks in advance!
