[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, ... -- SoniaToday'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. -- SLUG - Sydney Linux User's Group - http://slug.org.au/ More Info: http://lists.slug.org.au/listinfo/slug

I could use different domains ([EMAIL PROTECTED] and [EMAIL PROTECTED]), but that's messy.. LDAP is the way to go. OpenLDAP works really well for this. It can also be used to provide SMTP authentication, POP/IMAP auth, webmail auth, from a single username and password. LDAP routes mail which it receives and it can do it based on MX (domain) or a static mapping in the user entry. * have a multi-site email address book? I imagine something with LDAP; what client app would I use? Again, LDAP is your friend, that's what it does... * have multi-site calendaring? I know I can do things with Ximian Evolution for individual users, but multi-user multi site... I've not found a very good solution for this yet. -- SLUG - Sydney Linux User's Group - http://slug.org.au/ More Info: http://lists.slug.org.au/listinfo/slug

That reads wrong LDAP provides a username - host mapping which the MTA can use to correctly route mail. It works really well with 'global' mail platforms. We've just setup the same servers in UK/Europe/NZ/AU all using a single replicated LDAP database. When mail arrives in UK it checks the LDAP record and, if the mail's not for a UK bod, it routes it to the correct host in $other-country. Hope that's a bit clearer -- SLUG - Sydney Linux User's Group - http://slug.org.au/ More Info: http://lists.slug.org.au/listinfo/slug

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.
