So the problem is limited to just one "domain name" (@bar.hornet.com), 
right? The others are working fine?

Ugh... that's a Zimbra setup. I've never worked with Zimbra's Postfix 
(AFAIK, Zimbra uses its own Postfix implementation).

I would start looking at your Zimbra's/Postfix virtual domain 
configuration (that involves "virtual_mailbox_domains", 
"virtual_mailbox_maps", "virtual_alias_maps", "virtual_alias_domains" 
variables) and also into your DNS's config file (MX entries for the 
"bar.com" domain). All of those should point to merrimac's machine as the 
host that manages e-mails for the domain.

You can also make Postfix to be more verbose with the logs by increasing 
the variable "debug_peer_level". Make the change at main.cf, reload the 
service and try to send a message again. Maybe you can get a clue on why 
your Postfix is forwarding the message to the other host.

(Don't forget to restore "the debug_peer_level" to the default value, as 
logs can be very verbose).
