I see.

"192.168.0.13" is hornet with Postfix setup to relay all the e-mails to 
merrimac, right? Then something looks wrong at merrimac's Postfix 
main.cf, it should be setup to directly delivery e-mails and not 
fowarding them again.

Can you post (or upload to www.pastebin.com) your merrimac's main.cf 
file? (you can remove/hide any sensible information that file can 
hold). That way maybe we can get a clue on what's going on.
