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.

That is correct. But merrimac is working correctly for the other hosts on the network, all in the same range, though the rest are running exim4.

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.

Attached below. Also note that all hosts are properly entered in DNS, both forward and reverse lookups work.
