Hi andybh,
I looked around at a number of distros for what I wanted and settled on SME. I haven't looked back! It has been perfect, especially as I am a relative Linux newbi.
I am using it to share a DSL connection between three of us; using it to host the two domains we have, with email and websites; using webmail to access that email remotely, all on dynamic DNS (script runs every minute to update if IP changes). I also have anti-spam and anti-virus installed (added on after the install). All this happens on a PIII-500 with 192 MB RAM and a single 20 GB IDE HDD. It is brilliant!
The install is a breeze - took me about 40 minutes on that PC. I ran the update script which is available from this site, which adds the anti-spam and anti-virus and other stuff.
Configuration of the server took less than 30 minutes - adding users and configuring things the way I wanted them.
Saying this, I ran this up a few times testing, but I literally had my server up on the net serving webpages and email within 2 hours.
Hope this helps a bit.
