G'day...
Postfix can do what you're after regarding mail directing. Check out the documentation at http://www.postfix.org/
What you are after is transport maps, which is controlled via the file /etc/postfix/transport - make sure you read the directions in the file, and that the main.cf has the transport_maps parameter pointing at it.
You'll have a configuration where mail travels something like the following (apologies to ascii art lovers):
+-------------+
Internet ------------| Postfix MTA |
+-------------+
| |
+---------+ +---------+
| |
+---------------+ +------------------+
| Sydney Office | | Melbourne Office |
+---------------+ +------------------+
Although you could omit the intermediate MTA and have one office pass mail onto the other if it's not destined for it.
Warmest regards
Mike

To: [EMAIL PROTECTED] cc: Subject: [SLUG] exchange migration pointers? |
My work is going through a painful multi-site MS Exchange migration at
the moment, and me being the Linux person, I said 'why don't you use
Linux - less $$ on hardware, more reliable, easier to manage, etc'. But
then I realised I wouldn't know how to do the stuff on Linux that can be
done on Exchange... ;-)
I'm quite comfortable setting up a Linux (postfix) mail server for a
single site, with spam and virus scanning, IMAP access, iptables
firewalling, etc, but how would I do the following?
* setup my mail servers so that mail for users at different sites
(Sydney, Melbourne say) gets routed to the correct sites? I could use
different domains ([EMAIL PROTECTED] and [EMAIL PROTECTED]), but that's
messy..
* have a multi-site email address book? I imagine something with LDAP;
what client app would I use?
* have multi-site calendaring? I know I can do things with Ximian
Evolution for individual users, but multi-user multi site...
This isn't a 'help me now' email ;-) - I'm just interested in any
pointers people have, things I could investigate further, ...

Sonia Today's Tip from Debian NewbieDoc....
Looking to use your Debian machine as a FIREWALL? No problem! Try apt-get
install ipmasq... After you've got your /etc/network/interfaces file set up
properly, ipmasq will save you lots of work, setting up firewall and routing
tables automatically.
