Postfix minimal configuration
What is the minimum I have to do to configure postfix to accept incoming SMTP messages and store them somewhere? I need to set up a mail server in a real hurry, it doesn't have to do anything fancy, just be the MX record for a domain containing 3 mailboxes for a couple of weeks. I don't really need pop or imap access to begin with if I can log on to the localhost and read it on there.
Or if it's easier to do this using sendmail let me know what I need to do ...
The only tutorials I can find are extremely long winded and involve steps that aren't necessary for what I want to achieve.

Insert this in your /etc/postfix/main.cf last of all
myhostname = your.host.and.domain mydomain = your.domain mydestination = $mydomain mynetworks = 127.0.0.0/8
All emails would end up att $LOCALUSER@$mydomain
If you want to set some alias on emails a simple VHOST configuration would be quite easy to set up as well.
virtual_maps = hash:/etc/postfix/virtual
And this file should look like something like this:
If you wish that all e-mails with unknown recipient address to be forwarded into a certain user add one line in your virtual file like this

I've done as you suggested and restarted the postfix server service, but it seems that port 25 is not open on the computer as I can't telnet on to it from the Internet. I have configured port forwarding on my firewall to route port 25 to the NAT address of my Mandrake box. How can I open the port? I had read that once you have configured your MTA the port would just open but it seems that is not the case!
The strange thing is nmap shows port 25 is open?!
