Actually, NFS can work quite well. No, I haven't set up any system utilizing NFS for more than base Linux installs - not because it doesn't work, but because I don't need to scale up to anything that large.

No experience here with that system, to answer your original question.

Basically, what you're doing is synchronizing two servers to actually hold the data, then you have two mail servers that are accessing data through NFS - to internal machines. Benefit is that your data isn't actually on any machine directly connected to the Internet, and if any one machine drops, you don't lose much, if anything. Downside to this is that you've added at least two levels of complexity to the solution, and increased the points of failure by a large margin.
