[NTLUG:Discuss] An idea about the next presentation

[. Daniel]

If there's not already something planned I'd love to see a detailed 
installation of a very tight anti-spam email server configuration.  I'm 
ready to learn from whatever example is set forth in how to block spam in 
the most effective ways possible.

I'd like to see how to block incoming mail by IP/country ranges.  I'd like 
to see an implementation of this "grey listing" I've heard so much about.  
The anti-spam measure I have in place at the moment, "Spam Assasin" is 
effective but not effective enough lately.

Anyone as passionate about teaching this stuff as I am about learning it?
