[exim] Basic Setup Assistance

Hi all

I am new to exim and am looking for the best way to limit access to my
server from a list of IP addresses and also the best way to block
spammers (either IP addresses or mail addresses).

I have had a look around the web and the documentation and am a little
confused by it, so nay assistance would be appreciated.

Also, I had postfix installed with which I could view my mail with Pine
on the server but now I cannot. Are there any settings that I need to
change regarding default mail box delivery?

Thanks in advance
