    Default [SOLVED] Incremental migration from postfix to Zimbra

    Hi, everybody.

    I'm evaluating Zimbra Collaboration Suite 5.0 Open Source Edition in a Centos 5.3. It is installed and running perfectly.

    In my network there is a Postfix 2.4.7 serving mydomain.edu and it is the only authorized to send or receive messages from outside. It is configured with LDAP but using legacy schemes, so users databases won't be shared. I would like to run concurrently both postfix and zimbra and incrementally migrate the accounts from postfiz to zimbra and from my ldap to zimbra's ldap. So I would like that:

    • Both postfix and zimbra attend the same domain mydomain.edu
    • Posfix should be the only MTA to send on receive messages to internet (no change here)
    • Messages to @mydomain.edu should end in the right mailbox in postfix or zimbra


    Any ideas?

    Thanks in advance

    Have a look at the Split Domain article.

    Thanks a lot!

    That was what I was looking for. Now it works fine.

    In zimbra I did as the article said:

    $ zmprov md example.com zimbraMailCatchAllAddress @example.com
    $ zmprov md example.com zimbraMailCatchAllForwardingAddress @example.com
    $ zmprov md example.com zimbraMailTransport smtp:mail.example.com
    $ zmprov mcf zimbraMtaRelayHost mail.example.com

    in postfix I copied the zimbra file /opt/zimbra/conf/ldap-transport.cf to /etc/postfix, I commented the CA lines and added a transport map:

    transport_maps = proxy:ldap:/etc/postfix/ldap-transport.cf

    My domain now is splitted, with accounts in postfix and zimbra, every one can mail everybody, and postfix is the outgoing MTA.
