Just to put some notes out there, that doesn't seem like it would solve any
problems.
Your still stuck with a single point of failure, if your backend decides to
crap out your stuck with two dead front end boxes. Did you ever figure out what
was causing the 100% load ?
What I would recommend is looking at your my.cnf for mysql, and see if you have
it can squeeze some performance by adjusting the query cache, waittime out, and
other things.
Just some info on what we did, here what we have working and it been working
fine for over a year now.
What we have is pretty straight forward, and might help you in your situation.

A single QMAIL server alone even with crappy hardware cant host a few hundred

So I have two servers where are balanced connections and a storage with mysql
and messages.
The two hosts are with qmailtoaster and NFS to storage, I need do this because
the cpu load of one server was 100%, balance the connections was my solution
for both cpu and redundancy.
My NFS is simple, directories shared with (rw,sync,no_root_squash) only this.

I have one storage for NFS and Mysql
Please give us more information regarding your configuration. I have a feeling
that you have something going on that we're not able to guess because we're not
familiar with your setup.
Did you follow any guidelines regarding putting some things on NFS?
Have you used vqadmin at all?
