Hi, I'm using Postfix 2.5.5 with Amavis/CLAM. Also looking at adding SpamAssassin in the near future. I've also got Postfix Policyd V2 on my gateways. I've currently got this all running on Ubuntu (Hardy 8.04) and it's been fine so far. I have had one or two problems along the way, not with Postfix itself, but things like NFS at one stage (mail stores are on NFS mounts) so I'm considering moving away from Ubuntu as and when servers get replaced by newer hardware. This may be in the next 6 to 12 months as our current hardware is nearing it's limits.
I'm considering FreeBSD as an alternative, but I was wondering what people think of FreeBSD as a platform for Postfix. It's obviously not as easy to maintain as Ubuntu, but it does have a reputation for stability. Any thoughts, recommendations or experiences would be appreciated. Thanks Guy -- Don't just do something...sit there!
