I cannot get my MTA started. everytime when sending emails between two user account (all Zimbra users), it says cannot connect MTA and TRY_AGAIN...


Any idea why MTA failed to start. (I saw the message from /var/spool/mail/zimbra).

Are all the services running? What does the following show:

su - zimbra
zmcontrol -v
zmcontrol status

No idea without some more information, you can start with any error messages from the log files

[zimbra@zimbra bin]$ zmcontrol -v

I also asked you for some information from the log files.

Jason, is your Zimbra a new installation? It seems it has multiple problems. If it's a new installation. Maybe you just backup the emails and reinstall again? It beats fixing those problems one by one.
