How to set postfix to send/receive only locally?

[cayenne]

Hello all!

I'm still trying to figure out how postfix works. I actually got the virtual host howto accomplished for my own domain. It works fine.

However, I've got a box I'm setting up for another compay, hooked to my lan, and need to figure how at first, to only send and receive emails locally. I have it set up with the other companies domain name...but, I need to keep postfix from trying to go out and find its MX record.

Eventually, this box will be moved to the other site..where is will only sit and recieve emails relayed to it from their main email server.

I'm just starting, and trying to send email on the box locally only between two local users to test my initial setup. My next step will be to set it to recieve email from my local working email server to a local user which will actually be a perl script to process the email it receives.

I thought I had a small clue how to get started on this, but, I'm lost.

Could someone give me some pointers on the postfix settings I need to look at? I've got some books in front of me and will study it and other info...but, I'm just kinda lost on where to begin.

At this point, I have tried setting :
myorigin = $myhostname
inet_interfaces = $myhostname, localhost
mydestination = $myhostname, localhost.$mydomain $mydomain

(I even tried it by removing the final "$mydomain" on the mydestination setting)

mynetworks = 127.0.0.0/8

I put the users into the /etc/mail/aliases file and ran newaliases

I think I'm just missing a central concept here on smtp....and could maybe use some pointers on what I really need to be looking at in the process.

Thanks in advance!!
