I'm considering migrating to mdbox... wondering what you consider 
'healthy' rotation size.

I generally try to avoid changing defaults whenever possible, so, do you 
consider the default size of 2MB too small?

I guess though that it depends on usage. Since we get a decent number of 
large attachments, maybe that is a good reason to bump it up?

Thanks,
