Try looking for a netapp or something else for central datastorage and a
loadbalancer..
We have a Alteon AD3 with a couple of smtp-servers, a couple of
imap/pop3-servers and some ldap-servers. All mail is stored on the
netapp and all smtp-servers and imap/pop3-servers are identical.
For Ldap we have one master. The slaves get their data through
replication, not via the netapp.
This setup is proven to be very scalable, when you want to add another
20k users, just add some servers :)
Unfortunately I don't have serious documentation about the setup, but
you can mail me off-list about the setup if you have any questions.
