OT: Security Guides?

[Jonathan Roberts]

Hi all,

This is slightly OT, but I think you may well be the best list to
ask :) 

I'm thinking about setting up my own server, but if I do decide to do
it, I plan to do it right. This means I want to make sure it's properly
configured and secure, and that it doesn't end up hosting some dodgy
content or relaying spam around the internet! Does anyone have any
suggestions for reading that I can do to help me in this quest?

I know people on this list have been working on a security guide, but
I'm not sure if it covers the topics I need or not. Any advice would be
really appreciated. 

Jon
