Welcome to the forums,

Start with Incoming Mail Problems - Zimbra :: Wiki
Some key points:

dig mx domain.com
dig any domain.com

You can also use Pingability.com
(If you don't feel comfortable posting your domain name, you can PM any employees/mods who respond to this post if you would like us to check.)

Can you telnet to port 25 on that box? (from the outside - not any boxes on your lan)
If not: Firewall or even your ISP/hosting provider blocking port 25?

Do a tail -f /var/log/zimbra.log
-Do you see the connection attempts?
-Any errors there?
-Check the differed queue

If that appears ok, then tail -f /opt/zimbra/logs/mailbox.log do you see the mail showing up there?
-If not, the next question would be in regards to your dns setup...does this box have both a private & public ip?

host `hostname` <-- backticks not single quotes and use this command as is

If behind a NAT you may need:
