Hi,
I guess the title isn't much help ;)

local:
I am running on Gentoo with kernel 2.6.17 and postfix 2.2.10. I have managed
to host several domains on the same box using virtual domains and mysql. All
of this is working fine.

domain: domain.com

remote:
I am running on Gentoo with kernel Gilles and postfix 2.3.6. All this box
should be able to do mail wise is send emails out.

domain: domain.com

The remote host works fine(ish)... it will send email to all users that are
not part of 'domain.com'. My problem is, how do I get it to understand that
jdoe should be sent to the 'local' server and not 'localhost'
(remote)?

Am I making any sense? In short, the remote server thinks jdoe is on the
localhost and says the address doesn't exist when it is in fact on the local
server.

Off topic, I think I should have two servers running in parallel so any
pointers to documentation that can get me started on that are also welcome...
I am a newb but I can read documentation ;)

Thank you all for your help
