Hi there, everyone. I was doing the "Set Up Ubuntu-Server 6.10 As A Firewall/Gateway For Your Small Business Environment" how to and then in the first step of the third page where I should apt-get the courier-authlib-mysql. When I do this I get a message that says that this package isn't available but got references by other package. I tried to dowload it myself and install but it got dependences that got dependences themself. So I thought the mistake can be somewhere else since that how to is very simple. I shouldn't be getting this mistake. Any idea of what could be happening? Oh, apologizes for my english and my linux knowledge, I'm either a starter in linux and not english mother-languaged. Thanks anyone.
