Yes, Postfix does try to be very clever about keeping local mail local.

Consider carefully what IP address you have for your domain and how that 
fits in.

I use the domain "ml1.co.uk" to keep local lan stuff local and it works 
fine.

In /etc/hosts I have:
127.0.0.1               localhost.localdomain localhost
192.168.1.254           muse06.ml1.co.uk muse06 server

amongst lots of other stuff. I leave the IP address and reverse DNS for 
the NTL cable modem IP address set to whatever NTL set.

Look at the mail headers to see what postfix is doing. It is very good 
at /not/ losing mail. Whatever you post will be sent or will be on your 
machine /somewhere/.

Its all a matter of concepts and terminology. Socrates was giving people 
a hard time on such stuff a few thousand years ago!


And you have offlist mail.

Good luck,
Martin
