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

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).
