Yep we are, NFS server with 2x dovecot servers, mailboxes are Maildir and 
indexes are stored on local HDDs.  Using Mysql master-slaves for user/pass.  
Very reliable system, only real problem we had was when the NFS HDD failed.  
We now have a redundancy for that too :)
Timo has done some great work to get this kinda thing working.
