    Default Postfix MX Backup

    Hi all,
    I should activate an MX Backup server to store received messages when the Zimbra master server is down.

    I know the postfix configuration is really simple, but I would like to know the best method to get domains from Zimbra and to populate relay_domains in postfix's main.cf.

    Thanks in advance,
    Giorgio Salluzzo

    Welcome to the forums

    Do you want this to be a automated task ie. on a schedule the domains in ZCS will be dumped to a text file, transferred to your backup MX, and then updated in main.cf ? This may also be possible by a ldapquery directly from the Postfix instance.

    I think that an LDAP query from the slave should be a good solution but I don't have any experience with LDAP task.

    Can you help me, please? ...also pointing me to a page or an old topic it's enough to sort out the problem.

    Thanks again,
    Giorgio

    I would suggest you do a multi-server install setting up the MTA on your "backup" server. Just run the install script on the backup server, just install the MTA portion nothing else.

    The command to obtain the domain list is:
    zimbra@smtp:~$ zmprov gad

    It could be useful for somebody else...
