do you know postfix has also a very good mailing list ?

postfix tries to resolve FREEBSD1.FREEBSD2 using dns resolution. I don't 
know if you can tell postfix to use /etc/hosts.
try to add the name of your machines to the DNS, or use FQDN (like 
freebsd1.mynetwork.net).

with short hostnames (like freebsd1), postfix tries to add the hostname 
of the server it's running on
to the mail extension.

postfix won't give you good results unless you have a dns server up and 
running so you don't see messages like the one above
anymore.

hope this'll help
