Well, that depends on what you are trying to accomplish.

Myself - my email system is set up so that it has 2 databases running
- one is mirrored to the slaves to lookup information.

The other is the sqlgrey database itself, which I don't mirror as I
want my frontend systems supporting greylisting to have matching data
at all times without the latency of mirroring. Sure. MySQL is
fast...but a hammering server will generate multiple 'writes' with
the same credentials - I don't need that.

make sense?
