Oh and one final question, how does GlusterFS handle split-brain? Let's
say somehow the replication link became broken, but both Postfix servers
continued to operate...
This is documentation from 2.x series of GlusterFS but it still applies to 3.x:

Hello Jonathan,
I think what I am getting confused over is whether or not your GlusterFS
node are the same are your Postfix servers.
yes. They are.
I did a little reading
online, and from my understanding, you have 2 GlusterFS server and 2
GlusterFS clients.
Correct.

If you really need to spread the load, setup two servers with Postfix and
Dovecot. It would significantly reduce the complexity, and eliminate
your issues with multiple IPs. It would also reduce the bottleneck with
the proxy servers.

Define 'spread the load'.
You're taking a perfectly good server (or more), chopping it up into many
pieces so you can run many instances of Postfix and Dovecot.

If you secure your daemons properly, it is not insecure to give
customers direct access to the server. Even if they don't have direct
access to the servers IP, they are still able to talk to the server
