RH9 Upgrade question

[Bob Smith <bob netprt com>]

I've been using RH9 for the past couple of years, and it's time to upgrade.
I'm using it for mail serving, DNS, and webpages, essentialy as a server,
for not only my own domains but for a couple of others.

So, is Fedora stable enough, and robust enough, for this purpose, or do
I need to look at something like RHEL?

Thanks,

-Bob
