ZCS 3.2 Beta 2 on FC5

# After installation:

$zimbra-status

Starting mta...FAILED
postmap: fatal: file /opt/zimbra/postfix-2.2.9/conf/main.cf: parameter mail_owner: unknown user name value: postfix
postalias: fatal: file /opt/zimbra/postfix-2.2.9/conf/main.cf: parameter mail_owner: unknown user name value: postfix
postfix failed to start

Have user postfix:postfix to /etc/passwd

Still complains about not having permission to files. Cannot start MTA.

go into /opt/zimbra/libexec
and run
./zmfixperms

Works like a charm. Thank you!
