Hello, 
I have a lite gateway client that uses a database of IPs locations to 
screen out any countries before they get to iMail. Really cut down on 
the CPU load and still works well with Message Sniffer.
I don't see how this would work - the mails are coming from 
authenticated Web users, being sent to random US-based Yahoo and Hotmail 
addresses mainly. Since there's nothing indicating "Nigeria" in the SMTP 
layer (boy oh boy I wish Imail would add sender-IP to mail from the Web 
interface), this probably won't help.
