I have a zimbra installation on the same server as a drupal install, and when I installed drupal, it changed something in the postfix startup configuration.
Since then, when I reboot the server, postfix is started by root, and apparently that blocks zimbra from working properly. The solution to that was to kill the postfix started by root, and then to restart Zimbra.
While that was an OK situation for a while, I'd like for the server not to need this. I tried today to fix the init script set up by running update-rc.d -f postfix delete defaults, which made postfix not start at startup.
Now, when I restart the server, I have to start postfix for zimbra to want to start up.
Can anybody tell me how to get postfix startup configured properly? I'm sure this answer is on this forum somewhere, but I can't seem to find it.
