From Fedora Project Wiki
I'm a network/systems administrator in Boca Raton, FL. I have been using Redhat/Fedora since RH5. I use RHEL/Fedora for all of my production servers. I use fedora for all sorts of things such as: Virtual services (using qemu-kvm to run virtual production linux & windows servers), email (sendmail/postfix), email scanning (postfix+spamassassin+clamav+MailScanner, proxying (squid+clamav+dansguardian),PDF printing, Samba (PDC & AD),etc.
