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). - Oliver -- | Oliver Brandmueller | Offenbacher Str. 1 | Germany D-14197 Berlin | | Fon +49-172-3130856 | Fax +49-172-3145027 | WWW: http://the.addict.de/ | | Ich bin das Internet.
