[Sam Kava]

Oliver, 

Thanks. I was wondering if someone tried loadbalancing on a freebsd box.

The mail storage format should be Maildir - which is NFS safe. Access to

Maildir mailboxes by pop can be accomplished by courier-imap (it has a 
POP component) or the dovecot imap/pop server. I have both running in a 
single setup (for access to different mailboxes). The dir with the 
mailboxes can then simply be mounted from an NFS server. You should 
think about a shared authentication mechanism; we use LDAP for that.

It's quite simple. We even use more than one SMTP Server to handle 
incoming mails in this setup. Lodabalncing is done by an Alteon 180e in 
front of the machines (currently 3, soon to be 5).
