Take a look at http://www.dbmail.org/ for imap/pop3
you can have as many servers you want connected with the

Have you guys considered using Perdition to proxy/redirect IMAP/POP to
distribute backend storage to as many as backends as you want? You
wont need any SAN/NAS/NFS/GFS/whatever, just a user/storage mapping
(ldap, mysql, etc...), and you might even add spare or active/active
servers to each storage

Yes, but I prefer dovecot (since that's what we're running on the
backend POP/IMAP-servers). It
Perdition works WITH dovecot (or whatever imap server you use). It's
just a proxy - will redirect connections based on username, origin,

I read that OCFS2 is promising. If it works good, I can use an IMAP
