Topic: Service Seperation

Just about to delve into playing with iredmail.

Has anyone got any tips on setting up a multiserver array (shared storage over nfs) with service seperation, ie moving things like spamd / policyd / clamd to seperate servers as all of these things i believe work over tcp/ip connections so yes it will add a slight delay on things but seperating things out makes them more expandable and less load on the main imap/pop3 servers.

- Setup third server, ...

Oh, MySQL is just an example, you can use OpenLDAP or PostgreSQL. It's easy to setup one OpenLDAP master and as many slaves as possible.
