Re: [Dovecot] New mailbox format

I don't think PostgreSQL or MySQL had support for these kind of clusters yet?

I don't run mysql clusters myself, however:

MySQL Cluster enables you to:

* Cost-effectively deliver 5 nines availability using parallel
  server architecture with no single point of failure.

* Deliver the performance and high throughput required to meet the
  most demanding enterprise applications.

* Incrementally scale your applications in a linear fashion as
  your needs grow without having to invest in expensive hardware.
