/**************** Spam Prevention ************
	This feature is not for blocking incoming spam, but 
	for preventing possible use of IlohaMail for spamming
	purposes.
	
	This will involve a three-level approach.
	Level 1: Restrict number of recepients per email
	Level 2: Restrict number of recepients per session
	Level 3: Set minimum interval between sending
	
	In a restrictive setting, a spammer may be forced
	to send to 10 people at a time, once every minute
	and log out and log back in after sending 5 messages.  
	This should effectively discourage manual and automated 
	spamming.

	could cause excessive traffic, you can set the

	and they all have both refresh values set to 5
	seconds, they will generate 24 requests per minute
