BSD. FreeBSD is just about all we use. It gets much of the useful stuff from Linux ported to it like Clam, SA, Amavis, etc. and IMO it has a more stable development paradigm. And of course many useful things from BSD have been ported to Linux (and lots of other operating systems), such TCP/IP stacks, etc.
OpenBSD and NetBSD also have their adherents. I hear that a very nice firewall can be built using OpenBSD and pf. OpenBSD is written and configured to be quite secure. Here's a note from Kelsey Cummings on another list. Hope he doesn't mind the quote: > Sonic uses a couple OpenBSD PF firewalls internally and they have been > absolutely spectacular and allow for very complex network configurations. > > I'd be tempted to use PF on FreeBSD though since it's been ported over. > FreeBSD installs a lot easier and has better hardware support as well as a > larger community support network.
