I've made a total fresh install of all three servers. They now have a Debian 2.6 kernel, regular postfix removed and zimbra installed from the latest zcs-3.1.0_GA_328.DEBIAN3.1.tgz

Right after the installation, everything works fine, testmails arrive and everything.

Strangely the MTA tells me it's not working, while in fact it is:

zimbra@krab:~$ zmcontrol status
 Host krab.ugent.be
      antispam                Running
      antivirus               Running
      mta                     Stopped
              postfix is not running
              zmsaslauthdctl is not running
 zimbra@krab:~$ zmcontrol start
 Host krab.ugent.be
      Starting antispam...Done.
      Starting antivirus...Done.
      Starting mta...FAILED
 ... (lots of stuff) ...
 postfix failed to start
 saslauthd[8472] :set_auth_mech   : failed to initialize mechanism zimbra
 zmsaslauthdctl failed to start
 zimbra@krab:~$ which postfix
 /opt/zimbra/bin/postfix
# ps -ef | grep postfix
root      2562     1  0 16:47 ?        00:00:00 /opt/zimbra/postfix-2.2.9/libexec/master
postfix   2570  2562  0 16:47 ?        00:00:00 pickup -l -t fifo -u
postfix   2571  2562  0 16:47 ?        00:00:00 qmgr -l -t fifo -u

Also, the MX records in my DNS are set to use this machine (krab) as MTA.

After I bring all the machines down and bring them back up one by one (LDAP, MTA, Store, in this order), the zimbra services don't come up automatically on any of them.

I can start the LDAP through $ zmcontrol start
Starting the MTA with $ zmcontrol start gives the same output as above
Starting the Mail Store manually gives me this:

$ zmcontrol start
 Host langoest.ugent.be
      Starting logger...Done.
      Starting mailbox...Done.
      Starting spell...Done.
 zimbra@langoest:~$ zmcontrol status
 Host langoest.ugent.be
      logger                  Running
      mailbox                 Stopped
              tomcat is not running
      spell                   Running

So most things do come up manually, but without the tomcat, the webinterface remains unavailable which renders zimbra unusable.

As an answer to your question:
- The Store and the MTA can both telnet the LDAP server on 389
- The Store and the LDAP can both telnet the MTA on 25
- Not other telnetting on ports 25 or 389 is possible

/opt/zimbra/postfix-2.2.9 is running on the MTA, no other mail services are running on any of the hosts.

Thanks a lot for your help so far. I really hope we can sort this out (the only alternative to Zimbra suggested by my superiors is using MS Exchange )
