MTA error fatal: Connect to the Postfix showq service: Permission denied

Hi, Im having problems with my zcs multi server installation. Im not able to send and receive mail. Whenever I try to send a new message I get this error:

com.zimbra.cs.mailbox.MailServiceException: try again: Unable to connect to the MTA

When I check the status of each server services it all appears to be up and running. Using zmsoap -z GetServiceStatusRequest:

<GetServiceStatusResponse xmlns="urn:zimbraAdmin">

<status t="1321313280" service="mailbox" server="ms1.*.*">1</status>

I check the MTA zimbra.log file and this is all it says:

I have been doing some searching around in the forum and the closest I have come to a similar problem is this thread. The thing is that I already check and the partition appears to be working fine and configured correctly. Anyone has any idea why I cant access showq? Could that be the reason why I cant send mails?

I did that. And every command did what it supposed the exception of this instruction

ls -ld /opt/zimbra/postfix/sbin/postqueue /opt/zimbra/postfix/spool/public/* /opt/zimbra/postfix/spool/maildrop

and the reason I couldn't do that command was because postfix/spool doesn't exist. Is it normal for ZCS 7.1 to not have does files? Could that be the problem?
