If you want to see how far you can go with Open Source, you may have a 
look at what HEC (Hautes Études Commerciales) did here in Montreal:

If you want paid software, then you may have a look at Communigate Pro 
which i use at a client's site.  It's not too expansive, can  easily do 
clustering, runs on many OSes (I run it on CentOS 5), has a MAPI plugin 
for Outlook, includes a SIP server, etc.

I have 50 users with about 100 Gigs of mailboxes / Public folders and 
uses standards mbox / mdir as storage, doesn't need SQL, has a good WEB 
interface, etc.  I run data storage off  4 x Seagate SAS 15K 73 Gigs and 
it screams (Adaptec 3405)!  No %iowait at all.  The system runs on a 
Dual Core Opteron 2214 with 4 Gigs RAM (Tyan Transport TA-26 (B3992-E)). 
  It does many other tasks (Corporate FTP, Licence management server, 
SSH Gateway for road warriors, RSync Backup server for Winblows file 
servers, etc) and easily copes with the load.

Backups $ restore are very easy.  Upgrade and migration to another 
server is a breeze.  All is contained in one directory.

I'm in no way associated with Communigate or Tyan, it was just to share 
my experience.
