I decided to try the 6.0 beta, and something seems to have gone wrong.

Here's the behavior - during startup:

Starting logger...Done.
Starting mailbox...Done.
Starting memcached...Done.
Starting imapproxy...Done.
Starting antispam...Done.
Starting antivirus...Done.
Starting spell...Done.
Starting mta...Failed.
Starting zmmtaconfig...zmmtaconfig is already running.
eval: 1: Syntax error: EOF in backquote substitution
postfix failed to start
Starting saslauthd...done.


Starting stats...Done.

I get the EOF error whether I try 'zmmtactl start', or 'postfix start'.

I'm running the 32 bit Ubuntu8 version:
zcs-6.0.0_BETA1_1397.UBUNTU8.20090415162243
on my Ubuntu Hardy server.

Any ideas on where I can look?
