A mail server will by necessity synchronously write all messages to disk, this
significantly increases the number of writes for a message.
Flash storage wears out after a certain number of writes, and thus won't play
well with such things.
A server based around flash storage for the root fs and non-volatile RAM for
the queue might be OK. But non-volatile RAM is not cheap, see
http://www.umem.com/ for some prices.

2.6.x will sometimes panic on unlinking files, and has a few other issues too.
Purchasing a server with a 2.6.x kernel now may not be a good idea. If you
have a need for a huge server then you may be forced to 2.6.x for the
performance. But otherwise you are best advised to stick to 2.4.x for the
